Is there a new consensus on answer headers?

Question

When answering question before I always used to use the "Heading" option present on the formatting box. This produces the following markdown:

## Heading ##

However, within the past couple of days my answers have been getting edited to change it to:

# Heading

Along with a comment usually saying something like "Use this format instead".

As far as I know this was never a problem in the past and my original heading even works for the leader boards some questions include.

Has the consensus on what headings to use changed?

---

My main reason for asking is I've seen a few suggested edits that do this and I'm not sure about whether or not to approve them. And I'd also like to save others the trouble of having to edit my answers.

Answer 1

The consensus is either # Heading or ## Heading, whichever you prefer.

This previous consensus supports ## Heading, but now-a-days it's pretty common to use # Heading. This answer is an attempt at a new consensus, allowing either format.

If you like the smaller heading better, use that. I'd recommend against the ### Heading, as it's a bit small (and obviously not just **bold**), but that's just my opinion.

Furthermore, suggested edits to do such things should be rejected, unless they add something else. For example, if they add syntax highlighting, or possibly

codeblock formatting 

instead of

backtick

But other than that, they should be rejected with either "Clearly conflicts with author's intent." or "Changes are superfluous".

1 last tip: sometimes, if you prefer the # Heading style, it's better to use ## Heading if the title is too long. This is most common on polyglot and advanced scoring challenges, which can have longer headers (or just long language names).

For example, take this header:

Python, Ruby, Javascript, R, Julia, Octave, Matlab (5 languages), 186 bytes

You can also write it like this, and it doesn't take up two lines:

Python, Ruby, Javascript, R, Julia, Octave, Matlab (5 languages), 186 bytes

Answer 2

Since you mentioned answer headers in general as well, use #Language or ##Language like Riker said, but then after that, it is pretty standard to use a format like this, using a comma, strikes, and bytes:

# Language, <s>127</s> <s>98</s> 95 bytes

Like this:

Python 2, 127 98 95 bytes

And if your language is supported for prettify markup, you can use <!-- language: lang-python --> or something similar for syntax highlighting.
