On Twitter, now you can send Direct Messages (DMs) to groups of up to 20 people. Twitter users, you just got a great new way to collaborate with groups of people, inside and outside your company, from the broad universe of folks who are already on Twitter. IT folks who still need to control external communications for security or regulatory reasons, you just got a big new headache.

Announced January 27th, and with roll-out complete on January 30th, I got the updated iOS & Android apps between Friday and Monday. I know I’ll be using this feature!
