I've said for a long time that I'd rather see something that functioned much like Facebook does (or did, rather, maybe 10 years ago) but was completely supported by subscription. Let me pay something like $5/month and in return no funny business, no stupid manipulation to get more page views, etc. Just a place I can interact with friends and family.
But nobody would pay for that, even if that's basically what they pay for it indirectly through the products they buy.
