“I’ll be careful.”
A friend once pointed out to me that if you have to tell yourself this, you should stop whatever you’re doing (e.g. pouring bleach while wearing your best shirt) and reevaluate.
Get yourself a good app & it can give you recommendations. Personally, I’m using IceCubes & really like it.
Also, look up the FollowFriday hashtag to see who others recommend. Cory Doctorow is there, so are Jeff Jarvis & Amanda Marcotte.
