Summary: Every year brings new mistakes. In 2002, several of the worst mistakes in Web design related to poor email integration.Your feature ideas are great, and your obvious passion is a tribute, I think, to what we've done so far. So I'm going to have another one of those "out on a limb" conversations here about product design. (It's possibly too much for a blog like this, but...) there was something in a few of your postings that comes up often, and it includes the expression that the solution to a problem is "obvious." This has triggered something in me. A number of new community features will roll out next week and it seemed like a good time to bring you deeper into my world.

Lately I've been noticing the spread of a meme regarding "Dunbar's Number" of 150 that I believe is misunderstanding of his ideas. The Science of Dunbar's Number Dunbar is an anthropologist at the University College of London, who wrote a paper on Co-Evolution Of Neocortex Size, Group Size And Language In Humans where he hypothesizes: ... there is a cognitive limit to the number of individuals with whom any one person can maintain stable relationships, that this limit is a direct function of relative neocortex size, and that this in turn limits group size ... the limit imposed by neocortical processing capacity is simply on the number of individuals with whom a stable inter-personal relationship can be maintained. Dunbar supports this hypothesis through studies by a number of field anthropologists.
