If you've been around, imgur, basically. All the image hosting solutions before it (imageshack) and all the file hosting solutions before them. Yahoo.
"Crashing" in this context doesn't mean something goes completely away, just that its userbase dwindles to 1-5-10% of what it once was and it's no longer part of the zeitgeist (again, Yahoo).
the only way I can see that happening here (userbase dwindles to 1-5-10% of what it once was) is if another better service came about but I don't think that is what @bayarearefugee is talking about when s/he said 'come crashing down' ?

nothing is crashing down at this type of “volume”/user base…
