Scratch

I'm abandoning averr to make a new website.
I can't decide between:

• A site dedicated to complaining about issues which annoy you.
• A site for rating and discussing other users' taste in music, film, literature, etc.
• A private proxy.
• A simple, fast, clean organizer.
• An online portfolio-type thing for showcasing yourself, your writing/art/music/websites/inventions and commenting on other peoples' profiles and work.

Which one do you think would be the most useful?
Would you use it?
Other thoughts?
