It's interesting how old memes stick with us and have a nostalgic feel to them. Things like "Harambe", the "such wow" doge, YouTube shorts, etc. don't make such an indelible impression. Homestar Runner, zombo.com, and "all your base" elicit actual feelings.
Maybe it's getting older, or maybe it's the fact we're now increasingly innundated with content. Perhaps both.
Very occasionally I'll run across something which makes me think of the 'You can do anything at zombo com. The only limit is yourself.' line.
To your point, I think it's definitely a combination of both. The interwebs are so large now that it's less likely others see the same content. I remember the exact circumstances of when I saw the superfriends wazzup[1] video, laughing at Robin's shaking hands, where as I couldn't tell you anything about most of the top 10 memes of 2015.
Uhh, based on what? The only difference is the nostalgia
Which led me back to "End of the World" and a bunch of other Flash animations. Back when Flash was used by animators and not advertisers and malware authors.
Part of the difference is that viral things and memes of old had a longer time to 'burn' and didn't go through the flash overnight explosion that modern ones do. All your base would be posted umpteen times on a forum as it reverberated around the internet. Now all that happens in a day, and people get tired and burnt of it. It also helps that news organizations try to get in on it, which helps to kill off viral things (Harlem Shake, Gangam Style, etc).
Memes that have truly earned their classification.
You know what else I missed and saw latter that ellicits nostalgia? The Show. Any Sports Racers out there?

Next step is definitely trying face detection in the pipeline. So you can do Snapchat style filter art ;)
But its super hard getting it to run in web media stream capture at even 30 fps!
Zombo.com amazingly still gets something like 600k visits a month according to similar Web.
It would be useful if the plugin saved the filter settings from last it was used.
