I think the key for me is subscribing to more posts than I could ever possibly read, and giving myself permission to not have to read all of them.

Much like I used to read a newspaper, I've turned google reader into my information aggregator. It alerts me to daily podcasts, local/regional/national/global/financial news, interesting articles, etc... I read what's interesting, throw the rest away, star whatever I may want to revisit or leisurely read on the weekend, share whatever I want people to see on my blog, and 'mark all as read' when I start my weekend.

I skim whenever I'm waiting on a build or have a spare minute between meetings, but I separate out into categories things I'd like to read and things I may read if there's extra time. I spend about 2-3 hours a week in google reader, but much less time wading through comments and ads for a net gain.
