Interesting, I'll keep that place in mind. For now, I'm content to do here plus the three sites I listed above. But that seems like a good site for sharing content on a more ad hoc basis.
As I said please take your time, just like finding an actual house to make a home takes time and a lot of soul searching so does finding a "home" that feels right for you on the big and small net. Good luck, I hope to return and contribute here soon.
