The deceptive thing about systems like this are that the average is meaningless, as the distribution is not a bell curve. There are, yes, a small core of highly active users, but the decision about who goes in that core is totally random, since the distribution of links per user is roughly a power law. Both del and spurl get most of their activity from a small group of highly active users, but bigger systems benefit from both higher heads *and* longer tails. -clay _______________________________________________ discuss mailing list discuss@del.icio.us http://lists.del.icio.us/cgi-bin/mailman/listinfo/discuss
