Hubs and short messages are the future

I am kind of imagining a Twitter-like hub service of the future. Short, sharp, “what’s up in your world” messages: “you’ve a new email from Des”, “Jim’s just got some cool sofas” or “Jason invites you for a beer in Beijing”. Funnelling everything through a constrained service— Twitter allows you just 140 characters to make your point —means it would not be overwhelming. Just a tap on the shoulder, a polite note via text to your phone (or whatever the future’s short messaging service is). There’s no need to read your email now, but we just thought you’d like to know you have a couple waiting. Your buddy is having a barbeque like, right now, get some beers and head on over. Ubiquitous connectivity without being overpowering.
