I'm unclear as to how I should respond to a critic who commented on two, old, questions:
He added the words "how to" to the title of both, appears to have down-voted both of them, and posted a comment on both, cryptically suggesting that I learn how to ask questions on Stack Overflow. I'm certainly open to improving my questions, but I don't see how either of these violated "google results" or Stack Overflow's "How to ask questions", as my critic suggested.
I'm quite happy to dismiss this as serial down-vote by a disgruntled user (as has been discussed here on Meta many times; I'm not trying to reopen that conversation) and let it rest. But, this is the second time this has happened to me, so I'm open to feedback on how to improve my questions, if that is indeed the issue. Furthermore, I work hard to be constructive in my interactions on Stack Overflow to avoid offense, but if anyone thinks I stepped over the line, let me know.
Update: In retrospect, it appears that my critic believed that question titles must begin with "how to" (not to be debated here; see How do I write a good title?), and for some reason singled out two of my really old questions for disparaging comment and down-vote. Thanks to the assistance of many (especially the moderators), this now has been remedied.
