A Tangled Web is by Grognardia blogger James Maliszewski. In this article James explores the origins and history of Drow in Dungeons & Dragons. While it is short, A Tangled Web is an exceedingly well researched piece that is worth the time to read. Here is my favorite point of interest by Mr. Maliszewski, which I personally never knew from Greyhawk lore:
"Gygax even introduces the idea of non-evil drow in the form of “Nilonim, a dissident drow ... [who] led a band of rebels attempting to overthrow noble rule. He is of neutral alignment with a slight tendency towards good deeds.” Remember that Nilonim appeared in 1978, ten years before The Crystal Shard by R.A. Salvatore gave the world Drizzt Do'Urden, perhaps the most famous drow in the history of Dungeons & Dragons."
Good stuff. The best thing about this is you don't need a subscription to view A Tangled Web. So check it out and enjoy!
