Why do I use Flask?

I'm getting asked time to time, why I use Flask (what is Flask at all?) and what I do like most about it. Decided to post short overview on that - http://www.butenas.com/blog/why-flask/

I think we need more people telling why they use Flask, why they like it and tell their success stories. This is how we can grow community, attract new developers and make the Flask even better.

I would be interested to read your success story ;)
