dtgreene: 3. Why is my previous post "low rated"? What did I do in that post that is a problem? (I don't see any issue with it.)
Okay, I'll bite the bait. Just passing through, haven't been here in a while.
I'd say one of the reasons was probably because your post partially went way off-topic. Another reason would be the off-topic being about the use of a specific word of what was essentially an idiom (thereby taken out of context), and then used that off-topic as an excuse for seeking an offense where there was obviously no offense intended (much like the sensationalism curated by journalism).
It doesn't surprise me when a post with off-topic banter that is also uninteresting for the conversation gets marked for being hidden out of the way of the person who read it. Combining on-topic and off-topic in the same post can create an unnecessarily tainted post, and I would understand such a post getting hidden out of the way of more pertinent posts, too.
Personally, I think of the rating as about appreciation the post, as for me it's not about appreciating who did the posting. That's especially so since a post is then hidden from my own view when I've marked the post with "-", and always shown to me when I've marked a post with "+" regardless of its total rating. So in general, I mark posts to always hide them from my view, or to ensure it stays in view regardless of rating. For all I know every post on the World Wide Web is from a Turing bot, for I haven't met every person who has ever posted.
Maybe occasionally start your own "play on words" threads, or maybe "what each word means to me at this point in time" threads? There seems to me to be a lot of language lovers here that appreciate the nuances of communication, though that tends to mean being open to interpretation for making sense of what's being communicated rather than insisting on correctness or wrongness of word usage or structure. Of course it doesn't have to mean that, you could state in your own thread that want to insist on applying the concept of right/wrong to language use, though you might want to also clarify how to coordinate that with censorship, with personal expression, and with the development of new ideas.
Oh, and by the way, as for myself I have hidden all forum titles and all avatars in this forum by means of a cascading style sheet. It wouldn't surprise me to find out other people do, too, perhaps by other means. All I notice of the member info of any post is an arbitrary forum name, the date registered, and a supposed location. As such, maybe be mindful of chiding the posts of other people for not meeting up with your expectations of what should have been known about you from such arbitrary information. That's just one more way to come across as seeking personal offense, especially by turning casual conversation into fighting words.
