Is there another website like Fluther (details)?

Is there another forum or Q&A website similar to Fluther? And by similar, I mean a website whose population consists mainly of people that may tend to lean to the left. I don’t know if that sounds bad at all, but why would I go to a website with people of the opposite demographic (like a website for religious conservatives, for example). Also, would this website have a large amount of people as well?

This is just a question, by the way, I’m not leaving fluther or anything.
