I can't believe how quickly you guys are jumping to the conclusion of letting twitter die. It has a lot of value for common people to report problems and make them being noticed. For example, I've lost the count of how many people have gotten a better deal with companies that in the first place offered them a bad service / product, just by publicly reporting them on twitter.
Also lot of people get a quick support response just by typing "@company problem" no matter what company or the problem is. That's an incredibly easy way for users to solve many of their problems.
The world will keep going on without twitter for sure, but the hole that it will leave behind will be noticed.
I think that this real value will ensure that it never really dies. If anything happened to twitter.com, then dozens of little MVP short message boards would spring up. In fact, that might actually be an ideal outcome in the long run, especially if it leads to the formation of a standardized tweet data format and competing public APIs.
