Confused by the Twitter/Facebook thang

I thought that making different Web 2.0 applications update each other automatically was meant to be easy!

I'm currently trying to make my Facebook updates appear on Twitter and vice versa, but it doesn't seem to be working. Firstly, there seem two be two different applications - one that sends updates from Twitter to Facebook and another that sends updates from Facebook to Twitter. Is it just me, or is that cumbersome and a bit boring?

Help!

Oh - the pressure!

 I know that Tweeting is pretty much the same as updating Facebook, but the pressure to be witty and erudite seems so much greater on Twitter.

One thing I wonder is how to make Facebook updates appear on Twitter as well... That would be a useful and time-saving application. Maybe that'll be Thing 17.

Do libraries that use Facebook also have a Twitter account, I wonder? I also wonder if anyone has done a survey about whether Oxford students mostly use Twitter, Facebook, or some other social networking site. I think we'll probably stick with Facebook in my library, unless we can make our Facebook updates appear on Twitter as well.
