I'll admit that when I first heard the idea my first thought was "So we're going to be a second Hummingbird, just without the anime lists." But, you described it as a player.me, but with an anime focus. That isn't really attractive. I got bored of player.me within a week or two, and I imagine most people do. It's probably why it isn't exactly the most active social network.
I think expanding on the features lewd has to provide for its users is wonderful. Wanting to grow the userbase, and active amount of users per day is also something I'm happy you actively seek out. I'm hesitant on the LewdBook idea though. As it stands I don't think it's that great of an addition.
