HELP!

Calling all professional bloggers! I decided to change my layout today to something a little more funky. I'm trying to add a few more things to make it a bit more personal, but I can't seem to find all of the fun fonts that everyone seems to be using on their blogs! I'm a newbie...so I need some help. Please and thank you! Leave your suggestions. As long as it's free, I'm willing to give it a try! I just want a nice blog...is that so much to ask?!:)
