Make that two data points :)

The site is unwelcoming, and doesn't tell me why I am there. The About page is a lot better, but doesn't tell me why I want to use Gravity and not go to pre-existing communities. If I want to talk to people about video games, for example, I could visit NeoGAF or the Penny Arcade forums and talk to them.

If I want to talk about tech, I come to HN :)

Why do I want to go to Gravity? Why do I want to go to it over Quora? (which, BTW, doesn't answer the pre-existing communities question either)

The explore page reveals the functionality, but is overwhelming.

I didn't even get that far. I don't like watching videos on the Internet, mainly because I usually have other music playing, and they don't play so nice with linux. I don't want to have to stop everything I'm doing just to see what some - probably irrelevant - website is doing.

Get earcandy. It automatically fades music players once a flash video or a video player starts playing: https://launchpad.net/earcandy

Edit: regarding Gravity: I agree. While I do enjoy video's, because often they get the message across incredibly fast. This video doesn't. It's cute, but once I click explore and see a forum, it's a letdown.

The thing is, I don't want to have to stop my music just because someone wants me to watch their video. I like my music! What's the big problem with text these days?

Hear hear

Another one here! Not even a quick slogan to give some idea why I might want any type of gravity apart from the type that keeps me stuck on the world's surface.

Also, I don't have sound so even if I did give enough of a crap about a site I've never heard of that does some undefined thing to watch a video I still wouldn't have been able to find out.
