On this site, we want to see the actual code far more often than we want to see the rendered output, so MathJaX is not enabled for this site. If you want to show the result of some input, you need to ...

I completely agree, and I've been thinking along similar lines recently. I can only answer for myself and not for anyone else, of course, and only describe what I now do. What I try to do now is ...

I'd like to sound a note of dissonance. I understand [Bb]arbara's reasoning. But I think that it is flawed for two reasons: It is not clear from a post itself that there is a potential for two ...

I like getting these comments. I don't always notice when an answer of mine gets accepted - there's no automatic notification of that and the reputation difference is not unique. When an answer is ...

Luck of the draw. Whenever I submit a hacky answer to something then I know that I'm running the risk that someone's going to come along and say, "Just use package Y with option X and it all works ...

Most assuredly not. Whilst this place has its resident experts, the style is very much of a place where everyone can offer a helping hand and often a quick hack will do in place of a more measured ...

Let me expand a bit on my comment. I think that there are some basic guidelines for this sort of thing (note: guidelines, not rules). This is a question-and-answer site. So make the question bit a ...

Why do we need TeX markup? Firstly, what is usually meant by this is "We need TeX mathematics markup" rather than the full power of TeX. That's subtly different. Secondly, what benefit would that ...

I disagree. Firstly, with regard to the "pollution". I'm not usually an advocate of tags, but this is one case where I think that the tag system works. TikZ/PGF questions are easily identifiable as ...

I agree with the anti-piling on sentiment. If an answer is already below zero then I'll not vote it any further. I'll try to leave a comment explaining why I don't think it's a useful answer. ...

I frequently do this. The two decisions are almost completely independent for me. The only time that the presence of the duplicate would mean that I didn't vote would be if the original question was ...

I've done this before. My guidelines are: Keep the original possible duplicate. That was, after all, the majority view. If I disagree with this then I'd want to discuss it first (here or in chat). ...

Just a quick addendum to Paulo's post: it's also a very good question when assessed purely as an SE-type question. The actual question is very clear and easy to understand, well-framed, and it is ...

This is a judgement call. It may be that in their haste to provide a minimum working example, the questioner got sloppy. It may be that they really got it wrong. The most important thing is to ...

I would. Background: Before joining this site, I was certainly someone who wasn't afraid of hacking (La)TeX, but my hacks were just that: hacks. They worked, but that was about all that could be ...

Should Bill credit Adam for the code he reused? Yes. Is this behaviour acceptable? No. Should the answer to the above be "no", what steps the moderators should take to rectify the situation? ...

Maybe this is one of those ones like the latex tag. It's misused so much that pgf isn't a suitable tag. Whilst I can imagine a question being pure pgf (for example, something using the maths parser ...

I would like to have at least some connection to TeX in the question. I agree that it's something a lot of TeXers would be interested in, and is close to the spirit of the site, but I don't like the ...

This came up tangentially at https://tex.meta.stackexchange.com/a/2288/86. I'll copy the last part of my answer from there: I strongly prefer "TeX-SX" to "TeX.SE" (note the punctuation) and "TeX....

I support this feature request. Unfortunately, we (the site users and moderators) don't have any control over the CSS so we have to wait until this is brought to the attention of the SO overlords (...

Having now used the site a little, I can see that there is a case to be made for a way to included rendered TeX. I would argue that: It has to be true TeX. Otherwise, we can't be sure that what we'...

This is absolutely fine. The key things are what you've already mentioned: Make it extremely clear that this is an adaptation of another answer. Attribution is crucial. Make it clear what your ...

I'd also like to record my support for this. For this site to survive, it has to be one where the same group of people who ask questions are also those who answer them (broadly, that is). If only a ...

Although I suggested this in chat, I was being a little facetious. I think that this comes under the same rules as "best practices" and similar "meta" tags. If there is a situation where one thinks, ...

If one could guarantee that the 'tex' tag was used to mean 'this is a question about the bowels of TeX, if you don't know the difference between \def and \edef then don't read any further' then I ...

There can be reasons why it is useful to have a command-line method to convert PDFs to PNGs instead of letting TeX do everything - for example, if producing the PDF takes a long time and you don't ...

Tikz/PGF Answer: How can I invert a 'clip' selection within TikZ? Brief Description A method whereby one can specify the inverse of the usual clipping method.

I'd like to add a couple of "when not to edit"s. They are based on the following two side effects of editing: An edit on a question or answer bumps that question to the top of the active list. An ...

(This is basically the point made in the post that Rebecca links to in the comments.) Deleting a question also deletes any answers that have been given to that question. Therefore, once answers have ...

To expand a little on the comments, this site works best as a helping hand at the precise point where you get stuck with something when a small nudge in the correct direction shows you how to proceed. ...
