RSS is the best thing ever, period. I've found no other ways to follow websites online that even slightly improve upon it. And count in that anything from stuff like Flipboard to Twitter and similar.
It really is the best. No need to create and maintain another account, no need to reskim over read/intentionally skipped entries, filters for things you know you want to always skip.
I mean, Facebook is just a glorified RSS feed with centralized discover ability.
The hard part is the centralization / phonebook without that entity mucking it up. That's what made the Yellow Pages so effective, they separated the two.
What social network is not a glorified RSS feed with one or more means of messaging bolted on (including "likes" and "+1s" and "favs" and "retweets" and whatnot)?
