Top 5 Online Book Review Sites

Online book reviews are available at many sites. But which ones do readers like most? Lifehacker polled their audience to come up with a list of Five Best Book Recommendation Services. In no particular order, they are Shelfari, LibraryThing, Amazon, GoodReads, and GetGlue. I use Amazon, because I am a Kindle user, but Lifehacker’s readers prefer GoodReads.
