Good post here from Ian Delaney on a critical perspective on Twitter. Interesting stuff and I left a long (ish but very rambling) comment in essence suggesting that social media, as with any social practice, can and should be viewed with a eye to power relations. Power being a process of socialisation (and so not necessarily a bad thing), the way things are done to ‘legitimately’ participate in a community. Some aspects of power relations may be manifest in a number of indicators – numbers of follows, peer ranking, bespoke design etc. – denoting whose opinions may be more valued, as well as issues of simple access [to the internet, to broadband, to high-speed broadband etc…..].
Hope to see more consideration of a critical perspective on social media, web 2.0, enterprise 2.0 ……….
