Revish is here

Revish has just been launched. It is an alternative to LibraryThing. I've just registered and will need a bit of time to compare them. In its FAQs Revish claims that it is more about in depth book reviews that cataloguing and, unlike LT it does not have provision for tagging. It provides very readable guidelines for reviewers and, if people abide by these, the results should be worthwhile.
In Revish you can find books (from the Amazon catalogue), add them to your favourites, currently reading or other lists, review and rate them. You can also find out what like-minded readers are reading or have in their favourite lists. Categories appear to be in LCCRA format or may be taken directly from Amazon.
