I looked at many of the 2.0 winning sites. The ones I enjoyed most were the Fun sites and the book-related sites. Www.OneSentence.com had a good percentage of interesting, readable sentences - a bit like poetry. Www.FwdItOn.com included some really funny stuff amongst the entries. I'd love to publish on www.Lulu.com at some point - the how-to seemed easy to follow. Www.biblio.com was able to find an out-of-print reader I've been looking for; however it was in England at 10 pounds.
Ning.com didn't have anything to interest me at this time. Again, the aromatherapy sites were either ads or simply one-member-looking sites. Onward to Thing 12!
