XHTML and everything associated with it. Well okay, it's probably already considered dead, since HTML 5 has replaced in it about 95% of contexts. Turns out most people didn't want a web where a single syntax error could bring down a web page and went to the more relaxed HTML 5 the minute it was released. And while they won't die as far as their main purpose is concerned, I suspect webfonts will become a lot less popular in future. The idea of using them for icons has turned out to be a non semantic nightmare that's best done with SVG or plain old images instead. So the likes of Fontastic may not be long for this world...
