I organize my blogs by geography (MN blogs), discipline (PR, social media, mobile), clients (industry blogs) and other miscellaneous categories (fun, business blogs, etc.). With Feedly, I can scan headlines of these blogs in about 15 minutes a day (I give myself a hard stop). I look for posts that would be relevant to clients–and interesting to me. I bookmark those I think meet those criteria, maybe share them on Twitter/Facebook and move on. 100 blogs in 15 minutes. Believe it.
