Though “top 10” lists are interesting, they also draws readers into “top 10” myopia. Due to ranking, the popular climb even higher in a positive feedback loop. This normative behavior propels some sites far beyond their intrinsic readership or merit, for good or bad, while others languish in obscurity.

The wide variance evident in the data also makes ranking suspect.

By ranking only popularity, the list fails to recognize special capabilities of some sites, such as Blue Dot, which requires no login for e-mail recipients of shared links, Open ID capable Ma.gnolia, which also features groups and discussions, and Yahoo identity integrated MyWeb, the widest potential friend and identity silo available.
