My personal interests are too varied and too niche to have much overlap with anyone else. The number of people interested in compilers, cryptography, radio electronics, trad climbing, bouldering, bird watching (I post checklists to Cornell eBird), marlinespike seamanship, knots in general (I'm in the International Guild of Knot Tyers), who play the Great Highland bagpipes, Irish traditional music (tin whistle & bodhran), Scottish Country Dancing (in the Royal Scottish Country Dance Society), and live near where those birding checklists get posted is probably 1. Yet I'm likely to write about all of those interests. De-anonymizing me from that is probably not terribly difficult. The intersection of the RSCDS, IGKT, and IEEE member directories probably doesn't contain many people, so even knowing that is likely enough to narrow it down to a handful, if not be outright unique.
