Tomorrow, Yahoo will announce its second-quarter earnings and, once again, Wall Street is expecting yet another meh performance from the Internet giant.

In his “cheat sheet” report, Citi analyst Mark Mahaney’s take is pretty typical of the sentiment of investors weary of waiting for a rebound in Yahoo’s growth.

“From $15, we believe YHOO shares have upwards bias,” wrote Mahaney, “but we don’t have real conviction.”

That’s become the unfortunate norm for Yahoo, whose management has continued to struggle with a variety of issues, from its ongoing talent drain to an unexpected and still unresolved fight with its main partner in China to the troubles in its search partnership with Microsoft to the overall lack of ability to turbocharge its advertising and other businesses as has been long promised.

While it is certainly not for lack of trying, the prospect of Yahoo CEO Carol Bartz wheeling out another series of excuses for the lack of turnaround and — something many have been looking for most of all — a clearer strategic vision for the company on the earnings call on Tuesday, will surely not produce a dulcet impact on its depressed shares.

The stock has continued to dip well below $15 a share, down almost six percent last week and 13 percent for the last six months.

That’s why some think that Yahoo’s interest in bidding for the Hulu premium video service, which is being sold by its media giant owners, might be just the bold and risky move to get the company centered around.

With the online video ad business growing and the need for Yahoo to focus its many ambitions, some think Hulu could be a key piece in becoming the “premier digital media company” that the Internet giant has recently taken to calling itself.

By doubling down on what Hulu represents — that would be the premium online video business — it’s a fast-growing category Yahoo’s large sales force would be well-suited for.

In addition, a purchase of Hulu could give Yahoo some much-needed talent in the arena, including its CEO Jason Kilar and others.

“Of all the buyers, Yahoo is the most in need of a purchase to change its paradigm,” said one observer. “If it could not pay too much, Hulu would give Yahoo some differentiating that it really needs.”

Of course, paying too much for Hulu is a key consideration mentioned by all who are looking at it, including Google, AT&T, Amazon and others.

How to determine the value of Hulu’s content licenses, both now and later — given that once those rights expire whoever owns Hulu will eventually have to compete in acquiring the often high-priced material from Hollywood — is the biggest question they are asking.

Is that worth $1 billion or $2 billion? Can a new owner keep up the momentum needed to successfully maintain the Hulu business well after those content rights expire? And, of course, which company would be best suited to accomplish this task?

Yahoo certainly has all the potential to be at the front of that line, despite being managed erratically for far too long. But — also as usual — there is the endless debate internally over whether buying it will fix problems.

Whatever happens, most agree that something dramatic needs to happen at Yahoo, rather than the continual story of flatness that has been coming out of the company for far too long.

And we’ll all see if that’s improved after the close of the market tomorrow, when Wall Street is expecting Yahoo to report revenue of $1.11 billion on earnings of 18 cents.

That’s a revenue decline of two percent, which is not great, especially considering Google’s strong performance last week. Then again, it’s better than the first quarter’s six percent drop in revenue for Yahoo.

Like I said: Meh.

At least once a day, BoomTown gets a call from investors, analysts or other troublemaking types–you know who you are!–wondering why Yahoo is still plugging away in search.

With a declining market share in the arena and a search technology outsourcing deal with Microsoft, it’s not a bad question to ask.

But Yahoo begs to differ, introducing a new feature called Yahoo Search Direct at a press event in San Francisco today.

I liveblogged it, natch.

10:14 am: I was late, as per usual, but walked in just as the session was getting started.

Yahoo’s Chief Product Officer Blake Irving–looking fetching in a purple cashmere sweater–was talking about search.

He immediately turned it over to Shashi Seth, Yahoo’s head search dude, who immediately said: “Answers not links.”

Huh?

Actually, the product is pretty nifty, showing a lightning-speed box that shows more robust search results, although not unlike offerings from both Microsoft’s Bing and, of course, Google Instant.

While both have different takes, it is essentially a direction in which search brings in maps, photos, and–of course–advertising.

10:23 am: Wait, it was over before it started! Whoa. No more bells and whistles?

And I still was enjoying Irving’s sweater and I wanted to touch it, but that would have been wrong.*

Seth then took questions from the reporters.

“We believe the next generation of search…people are looking for answers,” he said.

Very true, but perhaps not so much from Yahoo anymore.

Still, Yahoo Search Direct is a laudable try and it’s also nice to see some innovation from the long-troubled company.

“We are the premier digital media company,” said Seth, parroting a new description of Yahoo that the Silicon Valley company is now using since its recent sales meeting in San Antonio.

I asked a question about whether there is a dedicated app for the tablet of Yahoo Direct Search, which sources had also told me was shown to the troops in Texas.

Yep! It will be ready later this year.

I also asked about how much all this search innovation was costing compared to return on the investment.

No answers from either Irving or Seth.

Someone then asked if there would be a lift in market share from the feature.

That’s the plan, Stan!

10:41 am: More questions about the comparisons to Google Instant. Of course, it’s the same type of thing, in the contest to win the King of Relevancy crown among consumers.

Google Instant. Yahoo Search Direct. Quora. My dentist, who seems to know everything. In case you didn’t know, dentists are very erudite.

Seth noted that even though Yahoo has only 15 categories covered in Yahoo Search Direct, there will be hundreds to come, as well as more features on top of this feature.

Personally, I want my search delivered to me on a silver tray by a man in a purple cashmere sweater.

Speaking of purple, the demo dude kept putting Elizabeth Taylor into the query box, which depressed me. Violet eyes now closed forever.

That was the real story today.

As if to round out the event, someone asked whether critics are right about whether Yahoo should still be in search.

“We’re in this for good,” said Irving firmly.

“Look, we are not focused on the past,” added Seth, who was not here in this very room at a similar Yahoo search event years ago, when similar promises were made about search going away from a page of blue links. “I don’t even know if you’d call it search in three years.”

What would you call it then?

“Find,” joked Irving. And later, “It’s actually ‘found.’”

Apparently, Yahoo was lost and now is found via Yahoo Search Direct.

*By the way, I touched the sweater, which was–in fact, Blake–periwinkle, which is a twee version of purple.

(You can see a video interview I did with Seth after the demo here.)

It’s not yet clear whether Beijing delayed the order because PC makers were having trouble supplying all new machines with the program or in reaction to the international outcry over it. In a letter to Chinese Premier Wen Jiabao last week, an international group of business associations that includes most of the world’s major technology companies, called upon China to abandon the plan, which it said “raises serious concerns for us and seems to run counter to China’s important goal of becoming a vibrant and dynamic information-based society.”
