I...have more credits than you do on ebookfling, I think...
I have a lot of lendable books but with the instant fling I got to "lend" them over and over again...
I like it but so many of the books are just niche and unappealing. Lots of erotica smooshed up next to Christian book and paranormal romances, most of it indie/self-pub. And the searching/filtering is crap, and they have a lot of books listed as available that really aren't.
