Show HN: Review my startup: Quora, a topic based question and answer site

Link to sign up: http://quora.com/hackernews

Quora is a question and answer site focused on getting really high quality, authoritative content on any topic that people are interested in.

The big idea is to try to get every question page to be the best possible resource for anyone who wants to know about the answer. One way to think about it is as a cache for the research that people compile by searching the web or asking others. The feeling you get when you see a Wikipedia article and you think "Oh, that's going to have all the information I want about that" is the feeling we want to create across a much broader space.

The best things you can do are asking and following questions you're interested in, answering other people's questions, and voting or commenting on answers.

Right now, you need to use your Facebook account to sign up. We might add other ways to join later on.

We're still in beta and are making a lot of changes and have a lot of work to do but wanted to get some feedback.

Thanks

Quora rocks. It's a great product, i'm using it a lot. Once you start to using, it's addictive.

Your photo was probably small enough that different croppings didn't matter, or at least weren't different enough for you to notice. Thanks for the feedback.

We have our own login system. We just use Facebook to connect you to people you know and get your photo. Having real identities for people and having people connected to other people who know them are important for the system to work, and we found that the best way to get those things was to require Facebook to sign up.

We might add other ways to sign up later.

Awesome! I've heard great things about it so far. On my iPhone but will give it a whirl when I get back home.
