I had the same, but recently I just created my own personal site for my notes. The main benefit that I did not expect is that, in theory, everyone can see it. This causes me to put more work into a note:

* To make sure that it actually is correct. Multiple times I discovered when reading the documentation that I only had guessed it sort of right and that there were some key bits of info that I had missed.

* To make sure that it is complete and that it gives just enough background information for those who want to use it without being in the exact situation that I was in. I.e. for myself in a couple of weeks/months.

There are more benefits. Like being able to structure it exactly the way you like it with links, tags, search, etc. And that you can show it casually to potential employers, who won't read a letter of it, but they can see that you actually put in work and understand some topics. This last point can also work for friends and colleagues.
