Commenting, and not voting, is frustrating. I'm also disappointed how few people vote, but don't view (read) the post. For example, this post currently has 387 votes and only 16 views.
Like you, I have found using Python/Flask on my website a real hassle. Instead, I use a combination of Javascript, PHP and MySQL.
HIVE is not a popular platform, we all have to accept that. It says 'over 40' now and that's still not many. Getting people to read your stuff is even harder, time is a precious commodity.
I tried to host this with Flask some time ago, and did learn something.. but what a pain in the arse, passing variables. To the web from Python and back again, so much hassle.
I never got around trying Django, but it seems to be the same idea.
Django's just as bad.
