I’d like to start a programming blog but don’t know what to do : learnprogramming

title – I have Java, JS/HTML/CSS, and C# knowledge, and some Python as well. I don’t know what to make it on, tho; my hobby is game dev and that’s an option. But I’m contemplating and really don’t know what to start blogging about – whether it be making tutorials, portfolios, opinions, etc. I’d like to just try writing about something of the above (suggestions also welcome) and also maybe earn some money in doing so, but I’m blanking when thinking on what to write on. I’d appreciate any advice from people who have run or are running coding blogs, or general suggestions from anyone. Thanks!
