As someone who refuses to participate in Facebook, I don't have a "social" alternative to get my news. I also don't find social dissemination to be at all on par with RSS feeds and I certainly don't want my news to be restricted to what my "friends" decide to post. If I want to read snarky comments about news headlines, I go to Fark.
Thanks to those who posted articles suggesting alternatives to Reader. I will be exploring options over the weekend.
