Nick O'Neill has bid Twitter farewell at least once a month for the past two years. First when Facebook let you change status via phone. Then when Twitter and Facebook integrated via apps. Now it's because of an API. Twitter hasn't disappeared yet.
Facebook is mostly used for actual friends (well more than Twitter) and limited to real life relationships. That's true at least for the core demographic of college students. Twitter is much more about networking with new people.
So despite having similar or close to identical functionality technically, they have very different functions.
Not only that, but more importantly, on Twitter you can follow pretty much whoever you like without a required acknowledgment from the followed person/organization. To be friends with someone in FB, both parties have to agree, which pretty much sets them apart niche-wise.
Hey guys, I know I've said it before but honestly I think this has a serious chance of removing Twitter. I'll put my money where my mouth is ... I'm working on programming another version of Twitter using just the Facebook API ... we'll see if it makes sense :)
Eh, I see a lot of professional-networking promotion going on on Twitter, and FB has always been geared more towards personal connections, I think this may impact some of the userbase, but it's not a death knell. Given that it's trivial to sync your Twitter and Facebook statuses anyway, I don't see many users outright switching.
Well, I just tried to sign up for FB and failed in every attempt. I allow session cookies, and that's what their privacy policy says they only use. So they are excluding at least some of their potential market.
People claiming that technology X will kill technology Y should most certainly make an attempt at understanding what technology Y is first. This person clearly does not.
I did this for a couple days and turned it off. My Twitter feed is very noisy, and looks retarded to the 30% of my Facebook contacts who don't live their lives in front of LCD screens.
