The only reason I made a comment to this effect is that I've noticed an uptick in articles about how Github is your resume/marketing yourself/marketing your OSS/how you should only work on 'important' OSS/some other silly notion. I want to believe this isn't a problem, but with open source powering so much, it appears that people want to be the next DHH.
I think there is something to worrying about software shifting to a heavily reputation-based economy (as opposed to one oriented around making things). Namely, in that shift, it rewards people who generate noise, regardless of the amount of signal contained. Polluting the well, in this case, results in everyone having to output a certain amount of signaling just to keep up.
It's entirely possible I am projecting some here, as I've struggled with this myself. I just don't want to always concerned with this tripe, because it's not the same at all as actually making software.
