Is the Twitter Sky Falling? Not for Us, Says TweetDeck.

Talk to developers who build Twitter applications these days and you’ll hear one of two things:

• Holy cow! We’re screwed!
• We’re fine. But the other guys are screwed.

Put Iain Dodsworth in the second category. The founder of the popular TweetDeck client says he’s not worried about competing with Twitter for users, but he imagines that other developers are.

Dodsworth’s argument: TweetDeck is a big, cumbersome application with an overwhelming array of bells and whistles, aimed at a relatively small group of people–he says he has “millions” of active users–who like that stuff. Twitter, he says, is happy to let him target power users with his app, while it goes after larger market segments.

But “those guys that have got just a Twitter app…that is potentially ‘filling holes’–they’ve got a new competitor, which they didn’t have before. And a powerful one.”

Is Dodsworth just spinning? Perhaps. But if so, he’s doing a very fine job of it. Check out the interview I conducted with him yesterday, where we talked about hole-filling as well as the competition between Twitter’s new ad platform and the rival one offered by TweetUp.
