I have Goodreads account too, and became a librarian to be able to fix information and add books that are missing.
I update my progress all the time, when I finish a book, or every evening my current progress on the books I read. Using their Android app is pretty darn quick, and I get a lot value out of it.
On the other hand, my Kindle has mostly Project Gutenberg or other out of copyright books, only bought a handful new ones, so I personally don't care much about the syncing with Kindle. Some people also complain about too much noise in their friend feed about progress updates, so I guess some thought needs to be put into the implementation.
