There's a joke that every web developer makes a personal page by first writing a custom bespoke CMS over a couple of months and then only using it for one "Hello, World!" post, but honestly, I've found that's been a great use of time for me. When I do real work projects, I've ended up saying "Didn't I solve this for my blog a year or two ago?" and then I dig up the code and reuse it. It's a great learning experience, and I think every web developer should do it.
