When I say "time lag was long" I mean several YEARS.
Also, for about the past 2 years there are SO many postings in fun that most posts "fall off" after maybe a few hours. On the rare occasions when I post there I usually get less than 30 views. I've even seen that happen with my reposts that originally got thousands of views, so it's usually not worth posting there.
That's one reason why users created the frontpage and MEMES_OVERLOAD streams.
