* Tech inclined, but non-industry friends just don't see the value of Twitter. The word pointless is used almost every time.
* Those that try it leave very fast. That's where the 10 tweets per person seems to be about right.
* The engagement just isn't there. I know someone mentioned the whole 90/10 ratio, but that's different here. Imagine if only 74% of Facebook users posted something or updated their profile. That's really really bad.
* I asked a room filled with 30 college seniors who come from good backgrounds / fairly smart / business students etc if they used Twitter. One person tried it and one person uses it for their job, not personally.
I'm not saying Twitter is horrible or Twitter is going to die. I just don't see it being the huge monstrosity of a multi multi billion dollar company a lot of people expect it to be. That's okay. I'd rather see it stick around for those that do value it, rather than die because it tried to become something it just can't be.
