Yes , I wanted to put a lot more but it won't let me.
Personally, I think there is plenty of room in the "About Me" area. You don't have to give you life history, just a brief history of yourself. I don't think many sites let you fill out a whole page about yourself. Some people hardly put anything there. I think it's fine like it is.
Doesn't matter to me since I never fill that out anyhow.
