A few commenters claimed that blogrolls were useless, but I still remember how invaluable they were for me when I ramped up on my reading, so I keep mine up as a kind of a public service to new readers. If such function is assumed as primary, the blogroll has to be short, best of the best. A short blogroll is also easier to update. My subscription list includes about 190 anime blogs of varying quality. Dumping that into blogroll would make it just as useless as said.
