This looks promising, although I'm not convinced that I sufficiently understand their privacy policy or restrictions on what member sites can do with my data.
So I'm not quite ready to give this a try. I'll keep a close eye on it, though -- this seems like a worthy experiment.
I signed up. I've been waiting for one service I can pay for access to all the sites I want without annoying ads or paywalls. We'll see if this is it.
