That would be useful. I guess the way I've seen this done sometimes is to use symbols like * † ‡ for content footnotes and numbers for citation endnotes? But that usually works on paper, where pages are short and you can see the content of the footnote at a glance. I'm not sure I've seen a solution for this that works on the web. It'd be nice to have an integrated Less Wrong footnote system so that we could test different ways of displaying the content. Maybe a hover-over-the-footnote-to-read-its-contents feature?

This works (if entered with the HTML editor):

<span title="hover text">blah</span>

Unfortunately, if I remember correctly, there are gaps in browser support for it. Also IIRC, using <a> works in more browsers, but the text will show up styled like a link unless some CSS tweaking is done.

That's just a title tooltip isn't it? You can set those in Markdown easily enough (eg. [display](http://hyperlink "hover text")), and you're not allowed any sort of markup inside the tooltip, and they have severe length limitations too. So it'd be a major compromise. (I have, painfully, added them to the frontpage of gwern.net, but no one has ever commented on them or given any sign that they are useful, so I've never bothered with putting them elsewhere.)
