What is the consensus around formatting? If things like bold and h1 tags are their in the formatting bar I assume it's ok to use them. I can empathize that one shouldn't abuse formatting since it would make the site look "messy" to say the least.
However I have some answers where I've put a heading (h1) and bolded a key phrase and some moderator has taken upon himself to remove it from each and every answer. If that kind of formatting isn't allowed why have it there at all?
if the normal formatting for h1,h2 etc is "obnoxious" I'd suggest decreasing their size and impact on the page. If h1, h2 etc shouldn't be used them why not remove them
