Weekend Update, 4.19.09

A look back at the week during which approximately 40 percent of the posts were about Twitter. Or at least it seemed that way.

BoomTown got the ball rolling by making a visit to Twitter HQ bearing pies. During a video tour of the premises, Biz Stone discussed rock stars and booze, and spilled the secret of the strange green deer. Later, co-founders Stone and Evan Williams were customarily nonspecific in a conversation about their revenue plans, and BoomTown was a little bit horrified to have become one of Ashton Kutcher’s million-plus followers–maybe even the one that put him over the top in his race with CNN to hit the seven-figure mark. Still on the celebrity tip (but off the Twitter one), BoomTown took a moment to appreciate the self-deprecatory stylings of Lindsay Lohan’s eHarmony spoof and to embed the video on AllThingsD.com. Finally, was there anyone this week who missed Susan Boyle’s virtually instant stardom on “Britain’s Got Talent” via Google’s (GOOG) YouTube? BT took a look at the journey the story has taken from television to Internet, back to television and back to Internet again.

Back to Twitter, MediaMemo took a look at its amazing growth as a service and as a phenomenon–the “hockey stick,” as one early investor describes the company’s trajectory so far. MM also looked at a study from the USC neuroscience group that says despite all the hype–or maybe even because of it–the human brain just isn’t built to digest information at Twitter’s pace. In the world of cable this week, just as folks were wondering whether Congress will stop the cable companies from charging by the byte, Time Warner Cable (TWX), one of the key players in the drama, backed away from its plans to do so. MediaMemo followed that story as well.

In this week’s Personal Technology column, Walt Mossberg took a look at the latest version of Apple’s (AAPL) MobileMe, and while he found it to be a big improvement over the product launch from last summer, it’s not without limitations. In Mossberg’s Mailbox, Walt answered questions from readers about displaying emergency contact numbers on a locked cellphone and the security of running Windows software on the Mac. And in Mossberg Solution, Katie Boehret took a look at Gwabbit, a program built to mine emails for contact info.

More next week.
