I should have done this a while ago, but hey now my profile is finally complete.
Come check it out if you want!
FYI I revenge all attacks :3
Probably C. I think. That was over 15 years ago so I'm not 100% sure. Could also have been Basic at the time.
Nowadays it's definitely Python though.
OK, I'm less familiar with flask, but for the front-end logic, jinja fits well into your needs, I think
I'd definitely recommend also using a css framework too, because it takes a lot of the legwork away from you. Most have JS dependencies, but there's Bulma, which is a no-JS one that's easy to customize.
Oh man, same boat. (Though for me I'm just making a whole blog instead; I found it more flexible to my needs.)
The best general advice I can give, is to define early and clearly what features you want, and to stick to that. If you get any idea for extra features along the way, reserve them for a future version. This will help you break down the work, and avoid scope creep.
Have you already chosen a framework for the front and back ends?
