I’ve been taught how to micro blog at an event called Social Media Camp. It’s a bit strange to get used to, at the event there was about 1 blog post going up every 10 seconds.
However by the end of the day I’d been brainwashed and started to see how it could be useful. It’s a bit better than facebook in a way as at least you have to keep things short, and you can link out to your own websites as well. It’s also good for keeping in touch with people that you meet for only a short time but who are doing interesting projects.
