It's not part of the public internet, that's probably the main problem, but I also have quite a strong aversion to things run by large corporations. At the moment I let google in, but that's it. (and they completely ruined my previous picasa-album sharing of my galleries of fractals, so I'm not hugely happy here either!)

I am more interested to find a passionate niche of ppl that really love the journey than getting general exposure, I guess that's another side of things: 2d fractals don't really have much mass-market appeal, but if you know what's going on there, it's a lot more interesting to follow!
