Sometimes you just have to scream into the abyss until the abyss screams back. Sure, you could post to facebook or tumblr instead but then we wouldn't know what you're thinking. Which makes us sad. So come on, tell us what you're thinking. Feel free to ramble or just post stream-of-consciousness stuff.
Some caveats: no spamming, and please wait at least 24 hours before posting after yourself (this does not apply if someone has posted after you) before posting a new thought (remember, you can always edit your post to include new stuff if the 24 hours isn't up).
