i started using the internet in the late 2000’s and still remember when you search for something most of the times it would return with a forum post … now its just random websites … if you ever need real and concise answer you have to add site:reddit.com at every search and since discord or twitter are not crawlable by these search crawlers they are not mentioned . Where did all those forums went…are there still active forums ?
Reddit killed forums and Discord took over some of their other functions even though is fucking terrible at it.
Facebook also played a large role in retiring the independent old style of phpbb/vbulletin type forums.
