This is a pretty good idea. Something that scans tweets and other publicly accessible social media for a list of known words and then compiles it into a report for potential employers would go gangbusters in the HR/hiring areas. It obviously couldn't get everything, but would be a big help for employers.
Sounds wonderful. /s An automated tool that disqualifies people from employment for something ill-advised they once wrote in college based on a naive algorithm.
ADDED: Of course, if you want to be an authentic disruptive Silicon Valley startup you'd offer both this service and a service for end users to expunge any online content that would be flagged by their employer service. Should be good for some fawning tech press writeups.
I'm sure people that don't get a job because of something they said in the past wouldn't like it. I don't really like the idea of not hiring someone based on behavior far in the past (recent public behavior on social media is fair game in my mind).
However, in terms of a startup product that companies would pay for, I stand by my claim that it's a great idea. After all, HN is ran by yCombinator and startups are kind if its thing.
