Share Web 2.0

I have always wanted to do a blog where i can share my thoughts with people and where they can share their opinions too. I have no particular subject i want to talk about just random things.
Do you have any idea where i can go? Thanks.

Is there anything I can do to make my profile somewhat cuter. I love facebook way more that myspace because it’s easy to find people and everything but sometimes I think it can be boring. Any suggestions.
