I feel exactly the same way, but there is an incredible amount of hostility to this website in this thread imo. I almost made a similar blog post to start my blog off this year (which I still haven't gotten around to doing), and I did a similar thing with a web domain I bought as a joke while drinking. After years of development, it was actually exhilarating to work on something that I have no deadlines for and can use as an outlet to explore technologies I never got to use but always wondered about. I get the same energy from this website.
I hate the expectancy of software devs to work on their own projects as a resume builder, but this site seems to be _specifically not about that_. On the contrary, it seems to me like the author is re-learning how approach something that they may have forgotten that they even like to do in a casual way, which I think is nice. In fact, when working on side projects I care about these days, I get annoyed by my friends constantly trying to figure out how I'm going to spin it as work experience.
