I spent today at Social Media Jungle Boston, organized by Jeff Pulver. Check out the twitter stream on #smjbos, if you want to see the back-channel chatter.
The speakers mostly (and understandably) looked at the interpersonal interactions of what is, after all, social media. However when I got up for my slot, I choose to talk about Twitter as a Universal Information Stream. Slides below or here.
I included an idea from Matt Volpi (about automatically reporting point-of-sale data and also DVR data), from his comment on this blog when I first previewed this talk and asked for input. Thanks, Matt! Others may also recognise their ideas replayed here as well, so please remind me if I owe you credit.
