So how does SW compare with Experience Project?

From my experience, EP had a more developed community that focused more on... well, sharing experiences. Here, I've seen a lot of posts that look more like status posts or is a "HMU" sort of thing. There's nothing wrong with that, but I don't remember EP having as much of it. I did take a very long break though and didn't even know EP shut down until recently, so I might be talking about a community that died out years ago. There still seems to be a huge age range, though, which is also good.

The actual site itself, SW is doing pretty swell as an EP successor. There's a lot of cool features and the interface is similar.
