Dunbar Triage: Too Many Connections
A very thoughtful article on Social Networking, with LinkedIn, etc, by Christopher Allen in his Life With Alacrity Blog. I have also been part of Linkedin for some time, but have not seen it as overly useful. I sometimes get a note or two from it, but it seems to be easier to just manage your contacts yourself ... do many multiple contacts links really work? As is suggested, its the quality of a small number of links that is more useful than sheer quantity.
