That's sort of been my approach as well. Folks that follow me on twitter or read my blog know they'll usually be getting a specific technical step-by-step tutorial, or perhaps some higher level business stuff, but I try not to ramble on my blog. Folks get emailed when I post something new there (if they signed up for that) and I try really hard not to invade their inbox for a (delicious, delicious) curried egg recipe. Notifications here are more passive so I feel a little more at ease waxing rhapsodic here.
