Perhaps the fact that such links trend well on aggregators like hacker news and reddit as well as micro-blogs like twitter is evidence to the contrary. You may not, but a lot of people still find it fun (myself included).
Are you being deliberately obtuse? Popular Reddit memes are "not always good"* because of their frequency and continuous presence. April Fools is once a year and [apparently] popular on HN, you can't seriously compare that to the sort of memes that "infest" Reddit.
* to some. I don't mind them, personally. And they're easy enough to avoid--as soon as I log in and I get my personal programming/comp.sci/math/netsec related subreddits, my personal Reddit frontpage is about as good as HN, with the exception that one of the two does not constantly shit on the other at every possible opportunity (seriously, and you say April Fools is "played out").
