Twitter's problem is that they don't even have the basic understanding of why they're successful. In the past several years there hasn't been a single change they've implemented that has improved things. The goal I guess has always been to attract the non-user.

But when I really study things most of the stuff that people think as fundamentally part of the service was instead added by the community and initially rejected by those running Twitter like use of the pound sign.

In fact when you look at when Twitter really slowed its growth was when they turned their back on that very community, especially developers. Anyone here actually believe that their experience with Twitter wouldn't be far better if there were still independent clients?

Twitter imho would be far better served to improve the service for those using it than randomly try throwing stuff at the wall in an attempt to broaden its appeal.
