Actually a fair and strong point.
Only thing I can think of as a counter point is that as the other anon says the memes change and the strong ones get repeated and changed.

Old memes are not the same as new memes.
And new memes are only found on the thread.
The archive is only updated sporadically.
Would it solve your issue about the archival if the archiving only occurs after a thread dies?
So fresh memes are only on the new threads.
