Have to agree with what others have said about the extension being the major flaw in this domain. Before properly investigating just how important the extension is on ccc's I bought m8s.us (albeit for a song) and thought it would attract some interest, especially with it being the text/sms shorthand for mates. I got zero response to appraisal requests on here and later realised that the extension really hurt the domain even though every major extensions (and many of the others) had been registered (most are either parked or don't resolve) and the 1.7 Million results in Google suggested it might have some value.
.info only really works for certain domains IMO, and I think they will likely take off when Google Knol gets properly underway, but I can't think of any knowledge subject for my1 that ties it specifically to the .info extension.
