Google Friend Connect is now available in beta to any webmaster looking to add a "dash of social" to his or her site. This service lets webmasters add social features to their sites by simply copying and pasting a few snippets of code — no advanced coding or technical background required.
Just had a few others try it on different domains/servers...didn't work for them either. I guess "beta" in this case means "not working". I see the problem I believe. The file "canvas.html" generated by their system does not reflect the domain or name etc. So their file "generation" script is not working.
