Since everybody and their granma loves twitter, now we have lists and top tens and the like. This, though, caught my attention: why twitter works:
Twitter, on the other hand, by having the deepest personal penetration (mobile phone) combined with the most ease of use (text message), has an effort rating that falls below most peopleâ€™s natural resistance to participate, and its positive reward ratio is much higher because people are far more likely to respond to a text message than almost anything else.
I like the idea of twitter as a Dunbar destroyer, (from Dunbar number), since I have long stated that the Dunbar limit is valid only on primitive environment where physical displacement is cumbersome and energy intensive. OTOH, twitter (and other social media), allows for a larger contingent: you still have to know them and keep them entertained, but the barriers of knowledge and perception are not constrained by geographical location, but on similarity of interests: Media facilitating the social.
