Since the date is palindromic, and the weekday starts with an F, it’s time for another instalment of Follow Friday! Here’s some people I recommend following if you’re on Twitter, and some enjoyable tweets/links for you to look at if not.

The stats tell me that 1085 people have read this month’s newsletter. Obviously I can’t go to bed until exactly 4 more have done so. #ocd

If this post is anything, it’s a list of people I recommend following on Twitter. If you’re a regular reader of this site, and NOT already following our editor Christian P, then you’re probably not on Twitter or you’re doing it wrong.

Tune in again at an unspecified point in the future, when I’ll list more things you should click on!
