I’m a fan of a site called Reddit. It’s basically a social news / social bookmarking site. In one of the many subgroups someone asked about personal projects that people have worked on. I shared my work about Universe Sandbox and within a few hours I was voted the top comment (when sorted by best, the default method, out of hundreds of comments submitted).

I hope to be able to duplicated this flood once I release Universe Sandbox 2.

It’s going to be so much easier to use and learn.
