I wrote the article in question. I stand by my general observations, but the points about reputation brought up here are excellent. There is not much reputation to gain from answering questions incorrectly but quickly, and yet people do it anyway. I wonder what is causing this effect; there seems to be no gain, but I guarantee you that if someone asks a Perl question, there will be 5 answers in 5 minutes that are all wrong. It is interesting and confusing. (As to how this kills the site, I know a number of people who are active contributers in the Perl area who are just turned off by this. The see a question, formulate an answer, and then see six slightly-wrong variants. This just makes them mad, and they move on to something less frustrating. It happens to me, for sure.)
Also, some people noted that the golf example from my article was not referencing any one specific post on SO. That's true, but there is a lot of stuff in the Perl section that starts, "Golfing this down a bit, ..." and then they proceed to do a poor job golfing it down. Again, shutting up would be a lot better than posting, don't you think?
This annoyed me enough to blog about it, even if it's not every post.
