My love for LibraryThing has been frequently declared--and documented. However, even before I joined LibraryThing four years ago, I signed up for a GoodReads account. Keeping up with my books online was new to me, and I wasn't sure which site would work better for me...and GoodReads was free. (LibraryThing stops being free at 200 books, but my $25 lifetime membership has been a serious bargain.)
Last week, I deleted all my books from GoodReads. Then I added (as imports from LibraryThing, via Excel spreadsheet) only the books I've read and reviewed on the blog and LT, and I'm gradually editing in the reviews and ratings. People seek out reviews on GoodReads, so it makes sense for them to be there.
My full book catalog, including TBR Purgatory, will stay on LibraryThing. The wishlist is now on Pinterest, which I think is the easiest way yet to record a book I want to read when someone else blogs about it--pin it up, make a note, and move on. But going forward (and going back five years, once I get them caught up...that may be a good Bloggiesta project!), the reviews will be cross-posted on GoodReads. I think I'm capable of keeping up with that, and I'm pretty pleased I've finally come up with a use for that account!
Where do you post your reviews, other than on your blog?
