I have almost entirely stopped browing r/dota2 in 2015 just due to meme spam and 90% of all top posts being some shitty ass meme. I can't believe these kids find any of that stuff even remotely funny. It boggles my mind really.
I decided to check that. Just opened the front page and loaded the 25 posts currently on the "top" page (not including the stickied thread):
Thread type: (note: i had to choose some tags because they weren't tagged)
Suggestion: 4
Artwork: 4
"This happened to me in pubs/Cake" posts: 1
Comedy/Fluff: 4
Complaints: 3
Disscussion/article/theory crafting/item interaction: 4
News: 2
bug/bug fixes/ request: 3
First posts:
Serious top post: 15
Meme/joke top post: 10
Percentage: 40%
Unless this is an off day, you have around a 50% extra unaccounted for.
edit:I could probably try to do this for a whole month provided i find a way to automate the process through which it gathers front page posts
