myopenbar.com (Chicago link) is a dandy little site that lets you know where to score free and/or cheap eats and/or drinks on any given night in your area (assuming 'your area' = NYC, SF, LA, Honolulu, Miami, or the aforementioned Chi-town). The places are rated, and visited personally by the website's bloggers, but who cares? It's free booze.

2 years ago I FPP'd FlavorPill, a company that sends out permission-based emails for books (Boldtype), music (Earplug), and fashion (the JC Report). They've since added ArtKrush (it's art, stupid! - nsfw) and Activate (world events) to their aresenal. In addition to the topic-specific mailing lists, they offer city-specific lists for London, New York, SF, LA, and Chicago. Sample issues are archived on the site.
