I think there is a market problem of attention. Search engines, advertisements, social media attempt to solve it. There is also the problem of unsolicited sharing or spam. How do you find the good stuff without reading through lots of stuff you don't want? You curate RSS feeds is one solution.

If you don't want to invest in seeking that author again into something you were freely getting that was good, then the sad outcome is the lack of effort/investment on both sides (not providing a RSS feed, not remembering the author's website or name)

See: why open source software is never good enough, even though it is free. See: if you don't invest in your blog/website, why should I invest my time into it?

I have the same problem with GitHub projects. People spend a lot of time creating a wonderful GitHub project (they focus on the code), which is good, but they don't invest in the README.md and create good documentation. So I might star it and forget about it.

If you're creating a GitHub project, please write copious amounts the ideas, mental model and thoughts on the README.md

It's probably entitled because I want to benefit from other's GitHub projects. But when I'm presented with a paragraph about the code, it would be a lot of investment to work out how it is built, how it works, what is useful about it.

Regarding caring if other people read my stuff, I would like people who are interested in the same things as me to read it or to introduce an idea I think has merit. But introducing ideas properly requires exposition. So I need to follow my own advice and create exposition for my thoughts for consumption by others.
