Best place to share code knowledge?

Hey :) I recently learnt a whole bunch of stuff about Notepad++ Search and Replace for multiple strings, and it really wasn't easy to find information online - not many Stack Overflow questions or other forums that had helpful questions/answers. I'd like to write an article detailing all the tricks and gotcha's that I found out. I was thinking of writing on Dev.to, or perhaps Medium. I would also like to continue writing helpful things in the future in the cases that I work something out that I wasn't able to resolve by googling. I keep coming up against the paywall in Medium - what would the programming community most appreciate? Is there any platform that would provide an opportunity for me to earn money from this (kind of like youtube I'm thinking)?
