Did this ever actually launch? I don't recall ever hearing about it although I probably wouldn't have remembered anyway. I also didn't realize lycos was still around!
It looks like it did. The internet archive crawled bits of Lycos Circles from 2005 to 2009[1] as well as the original eCircles all the way back to 1998[2]
