Self-promotion: I run Thinking About Things [0], a simple newsletter that is a single link every other day to something interesting. Many subscribers have told me they've learned about a diversity of new blogs through the newsletter.
Is there an RSS feed somewhere, or possible down the line? My whole day is drenched with emails so I try to stay away from them whenever else possible.
You can see some sample articles at [1].
