Why should I "play" this and not blog about programming? I still have to go through the usual technical interview when applying for a job. What's my incentive? I'm trying to find a reason to spend time learning this, because it doesn't translate into marketable skills. I can't put "Level 65 player in StockFighter" (because this might turn out to be a niche product that no one outside HN will know about), but I will definitely include "XSS research on Java Spring".
Note: I'm not trolling or trying to put the project down. I'm interested in it but unsure.
