This is a very cool site. I was able to look at a really old version of one of my community sites for Delphi programming that brought back many fond memories. On a practical note, members of the WeProgram.Net User Group user group have asked me to re-create the materials page from past presentations. This page was lost after we upgraded to DotNetNuke, but is available in all its glory here.
Tool or toy, this site is a keeper.
