I completely disagree; if anything, I feel there's more relevant competition going on then there's been in a while. Certainly when Tweetie was on top, I feel like there was very little good competition, although I never checked out Birdfeed. I'm currently using Echofon - it's not the prettiest, but it was the first native Mac client to support User Streams, does some really smart stuff with its conversation view, and actually syncs the last-read tweet between devices - something I've wanted for years now. Twitteriffic 3 on iOS was my previous favorite, and I still love how simple and elegant it is. I think 4 on Mac shows promise, but needs more functionality before I switch to it. I know several people who are using Oosfora, which I haven't looked at at all. I don't like it, but I know TweetDeck is still popular (especially amongst super-popular Twitter users). The question is, are there enough people who want an alternative to the official apps for there to be a market? The answer to that is still up in the air, but I have a feeling the third-party client sales have been pretty good the past few days.
