I hate when people having glaring mistakes on their Bebo/MySpace page. Like the kind of mistake that has been there for so long, you wonder if the person actually proof reads anything. A prime example: misspelling the word "pigeon" right after you've spelled it correctly the whole way through. What did that poor letter E do to deserve being replaced with another I?

Seriously though, that annoys me, as well as people who lengthen words for no reason, as has been mentioned e.g. "yhoo" - so not only do you type like a 3 year old, but you also like to add in things that really aren't needed. Great life you're going to have.
