Related: Community-wiki of abbreviations
Can we implement a Markdown or plain HTML (Hypertext Markup Language) tag to give more meaning to abbreviations used in questions and answers? I think questions and answers would benefit if this information was readily and immediately available. I personally try to avoid using abbreviations if I can help it, but I completely understand its common use by others who are familiar with RPG (Role-playing Game) systems (see what I did there?).
In HTML, there already exists such a tag, and it is supported by search-engines as well for SEO (Search Engine Optimization) purposes:
<abbr title="This is the mouse tool-tip text.">abbreviation</abbr>
<abbr title="Role-playing Game">RPG</abbr> <abbr title="Dungeons & Dragons">D&D</abbr> <abbr title="Non-Player Character">NPC</abbr> <abbr title="Game Master">GM</abbr> <abbr title="Pathfinder">PF</abbr> <abbr title="All Flesh Must Be Eaten">AFMBE</abbr>
While some of these examples may seem trivial to most of us here, people will come here for our expertise and by speaking a large amount in abbreviations we obscure the message of our answers (and sometimes questions).
Instead of editing answers to 'expand' abbreviations to their full wording, I think leaving them as abbreviations with a mouse tool-tip will educate readers in a fast and concise way.
Abbreviations with this HTML tag usually look like a hyperlink, except the underline is dashed or dotted, instead of a solid line.
