https://news.ycombinator.com/item?id=7105799This last past year, at DjangoCon US • Chicago, I had the pleasure of sitting at the same table as Jacob Kaplan-Moss for the Speakers dinner prior to the conference. Very cool experience. My first.
I brought up Flask and asked him what he thought of it. I had recently used it for a project for the first time and likely only did so because I was SUPPOSE TO BE FOCUSING on Django and preparing a talk about it. So naturally, I procrasinated and did everything but. It's been on my radar for awhile. I was attracted to it by it's documentation. Turns out, I really enjoyed it. It felt familiar because I've used Django for so long. I brought this up at the dinner table.
Jacob said something that took me by surprise. I can't quote him exactly--the wine and drinks were too good that evening, but it was something to the effect of "Flask is what Django should have been". Another fellow from our table chimed in and added "If only Django had existed before we created Django!" What he ment was, without Django, Flask wouldn't of had such a clear and smooth start. Django taught us a lot.
What I took from this was, both have their place and we have a lot to be thankful for, especially coming from the Django community. In regards to longevity, I think community is a major factor but these two technolgoies are both under Python, and I think the Python community at-large is what matters here. Hearing what Jacob had to say on Flask was sobering. There is no end-all-be-all, and both of these technolgoies have more in common than not.
