I have to disagree with you on this one. It's not about the technology. I think this is what we techies get mixed up.
I would wager to say that by now 95% of all Twitter users don't give a crap about the technology.
They just want Twitter to work.
Twitter solves a problem that people didn't realize they had before. The ability to easily see what people are currently doing - the 140 character limitation is a godsend for brevity.
Because Twitter invented that space, it is going to be VERY difficult to unseat them.
At this point, only Twitter can unseat Twitter - quite frankly.
