Some good stuff...
To add a little more flavor when I use drow as villains in my campaigns, I do make them more spider-like..or at least, one particular subculture of them.
This subculture sees Llolth more like a black widow spider than she is normally depicted... Her avatar to them resembles an almost Shelob-esque "Red Widow" drider, and she is much more bloodthirsty. As a consequence, the females of this subculture are cannibalistic carnivores, and males are a rare commodity. Only those males with exceptional abilities ever get to reproduce- the rest are thralls, and eventually, meals. Males are almost never seen by surface-worlders unless they enter one of their cities. Within this subculture, Drider-hood is a mark of Llolths favor, not her displeasure - her priestesses actively request this transformation, as do many of their culture's heroes...and Lloth indulges them. Among THIS subculture, the Driders are not sterile, either.
They are very powerful, but because of their societal practices, they are even fewer in number than their kin- too few to be a serious threat to the surface world. However, because their driders reproduce, they are growing in numbers very quickly...
One other reason I dislike Drow is about 15 years ago, I was at the local Ren Faire called King Richards faire. Its in carver, Mass.. Lots of people in costume, ect. There was a group of fair patrons dressed up like drow. Black painted pointed ears, black shirts and gloves for skin, black paint on the face, white wigs for hair, ect. Me and the group I was with, a long time gaming group wanted to kill them. This was a ren faire, not a DnD con costume contest.
