An interesting idea about microblogging (notably Twitter, but I have to mention its more sophisticated open source twin, Identi.ca) - that its most important impact is in "micro-politics," chipping away at the status quo. Makes sense that these tiny posts might erode resistance like water droplets, or build up an idea like a stalagmite through that same slow dripping.

One such idea that became stronger in this way was "It Gets Better," a message for gay youth. And ideas like this - whether empowering, questioning, informative and debunking, are being shared all the time.
