Make a free blog, blogspot.com, wordpress.com, there's TONS!!! Or use notes on Facebook although it is likely you will get a lot of crap from people on there and if it's stuff you don't want your friends or family seeing then not a good idea.
You can put what city you are from and then click "forums/polls" on the right. You can ask or answer forums and they aren't moderated from what I can tell.
