AFAICT, Randal, like you, I've made what one might call an "enemy" on here. It seemed for a while that every time I posted a new node, the first thing that would happen to it was a downvote. It seems to have abated and/or been absorbed by whatever other voting activity is going on. Frankly I think I brought it upon myself whining about it in the CB and in a msg or two. I think the first downvote was legit--bad title or too long or something. I was even more of a newbie than now, excited as a puppy about this whole deal and just as clumsy, and I asked in the CB what was up. I think I did that twice. Pretty soon, every post I made was getting a negative vote almost immediately. I assumed it was someone who was in the CB at the time but didn't investigate further. I didn't know the trick (it seems to me like a 'trick' since I didn't think of it) of checking who's on every time you get downvoted. But I don't know that I'll use it since I'm comfortably in Friar-land (and yet to use my moderation powers--need to lurk in that regard for a while longer) and whatever level of significance that would be next is so far out of reach as to be useless to think about. But I remember being pretty upset at the time, so I grok. I dunno, I think that a good attitude to take is that we're all adults here and disagreements and personality conflicts arise. Big deal. Whatever it is I am or was doing that offended one or more people, at least I'm getting it out of my system on an internet message board and not with my colleagues at work or my family (imagine some person who would discredit you to your boss and company management at every opportunity just because she didn't like the tone you took with her in a meeting once).
Who knows, every one of my posts has something that will offend somebody--sometimes I don't post follow-ups in a timely manner, sometimes I'll get say five responses to a question and I will only mention four of the posters' names in a subsequent reply, out of laziness or because maybe most of what one person said was covered by the other responses, even if that person's answer was pretty good. These things happen. Life goes on, for better or for worse.
Don't know exactly what I am trying to get across other than letting you know it appears you're not alone (I see another responder had a similar situation as well).
UPDATE: a) for misspelling and b) I spoke too soon about the "situation" having "abated!"
I like computer programming because it's like Legos for the mind.
