I use Scribd for pretty much all the reasons Blossom already stated.
Although I have always preferred reading on my e-ink devices, I have been reading on my Nexus for 3 weeks now and I really like it.
My local library doesn't have a large selection and especially not in my favorite genre romance. What they do have are more sweet and homey type. So I currently have 2 paid out of state library cards to get more selection. I am dropping one of those for the Scribd. And even though S&S is now letting their books into libraries the libraries won't be able to afford as many titles as there are on scribd and then there is no wait time for them either.
I would not be a subscriber if they didn't have the mainstream books and big publishers. These services I think only work if you have that content.
Like Blossom says, Scribd is a romance reader heaven. Lots of great back titles and series titles to catch up with. I didn't consider Oyster at all as at the time they didn't have an kindle app and that was all I had at the time. They now have a android app but there is no way to browse their complete catalog without signing up.
I had contact with CS at Scribd and they are friendly and helpful and really responsive.
I wish Scribd could get all the publishers on board.
