Today, I took part in Commchat. I'm sorry to say I hadn't encountered the hour long Twitter debate before. I will, however, tune in again. It's a collection of communication brains (PR mainly) debating the topic of the week.
Half way through I decided I'd capture the chat. I've just started.
30 seconds - open Storify, select Twitter, deselect retweets and search for #commschat.
15 seconds - to write the above
45 seconds - click "More" on the 20 tweet selection default to go back an hour and collect 180 results - pressing "add them all"
15 seconds - oh, Chrome browser wobble time...
