Nothing outside some large book publisher trying to make me write a book so that they have a larger pool of authors to discard (they ask 5 people to write a book on some topic, pay like 5k upfront and select one in the end, wasting time of 4 people). All my bleeding edge articles had zero effect on my marketability and all I got was requests for source code or article republishing from some freeloaders. No jobs, no worthwhile connections came out of it.
