Hi all,
While the map is incomplete (how can it ever be complete?), I think it is one of the few times, outside of David Aitel's writings about the cross-cut between the "underground" (for a lack of a better term) and subsequent commercial activity.
Based on my personal bubble, completely empirical evidence that you should take with a huge grain of salt the cross-cut is not the actual highlight here - the highlight is a temporal one. The generation of folks contained therein are the among the first two generations (or so) between the commoditization of Internet - essentially having first movers advantage on the space.
Anyway, felt like sharing this with the rest of the community here
