QA platforms and blogging platforms both seem to have finite lifespans. QA forums (Stack Overflow, Quora, Yahoo answers) do seem to last longer, need to be moderated pretty aggressively unless they are going to turn into homework help platforms. Blogging platforms are the worst though. Medium looked pretty OK when it first came out. But now it is just a platform for self-promotion. Substack is like 75% of the way through that transition IMO. People who do interesting things spend most of their time doing the thing. So, non-practicing bloggers and other influencers will naturally overwhelm the people who actually have anything interesting to report.
