If there is a killer app for industrial espionage in Web 2.0, it is knowing someone’s del.icio.us username. Monitoring a person’s links via the feed generated by del.icio.us is just an awesome way to keep an eye on someone — particularly if they don’t hit that checkbox for “do not share.” I am looking now at the links of the CTO of a former competitor, and, wow, he is up to some neat stuff nowadays!
Sometimes you can just take a guess. E.g., are these the links of the real Tim Bray? Maybe so.
