I imagine a better, probably open source de-centralized protocol will come, and indeed good folks are working on it. But my friends and audience are already there and I already know they're hurting, so I know it's good play.

Twitter works for me because (a) Twitterrific is a kick-ass third-party app that automatically disappears without my needing to interact with it, (b) Twitterrific exists because of the decision to make a kick-ass API in the first place, (c) the ways in which one can participate are plentiful, and (d) the constraints and lack of functionality keep it accessible and manageable.
I signed up for friend feed because I do that for lots of new social networks. I like that there is a record that integrates lots of parts of my online life, but honestly I don't want to go to a web site to get the information. I won't spend that much time there, and if I were limited to the Twitter web site for all my interaction with that service I wouldn't use Twitter. They serve different purposes and offer different kinds of barriers to participation.
I like the idea of Twitter Love Day rather than a Twit-Out. This is largely a success based on community involvement, so lets use that collective brainpower to find ways to make the service better. Twitter is doing their part by being so transparent, and trying to be responsive ... even when they want to run away and hide.
The thing I like about Twitter is that it's largely passive- I have Twitterific running in the background with Growl notifications. When the newest Tweets load, whenever that may be, they pop up in the top right corner. When I see tweets come in I usually remember to post, so then I load up Twitterific through a quick Quicksilver keystroke, type in my post, and hit submit.
Because I only message when Twitter has shown itself to be working by sending me the new Tweets I never notice the infrastructure issues outside of TechCrunch's post spam about it in my feedreader. I can see how it would be annoying for more active users, though.
The lapse time is particularly frustrating when using Twitter for Q&A or ad hoc discussions. These are exercises in which I expect quick answers. If I wanted to sift through a pile of Tweets all at once, I would just use email.
Well, if no platform means no conversation, then I'm going to say platform.
