I’m a big fan of the changes that have been implemented over at del.icio.us, with suggested keywords based on previous activity. It’s done in a really nice Ajaxy way, and like all the best incremental functionality I can take it or I can leave it.
But what I’m really interested in knowing, for practical as well as intellectual purposes, is what kind of impact this is having both on the spread of keywords being used, and the shape of the tail. Clay Shirky, who I met for the first time in New York last week, drew me a nice diagram showing how, on del.icio.us, as few as 12 users can give you up to 90 per cent of the keywords that will ever be used for a particular bookmark. There’s a clear shelf in the tail at 12 users, and then a steep drop-off.
So will that 12 become 10 or 9 or 8 with the new technology? Does anybody know?
