I'm sensing that Roman's Flask project was born out of frustration with people not getting his Werkzeug and Jinja2 projects - probably because of bad marketing. On 1 April he created a silly little microframework and did all the right marketing tricks (flashy website, code on github, references to "ninja coders" etc.). It was supposed to be a joke, but upon seeing how much interest the project got he went ahead and started glueing these components together properly (that's Flask). Werkzeug was a marketing failure but Flask builds upon these mistakes. The documentation is good, the name is excellent and he's attracted attention through GitHub.
I'm waiting for an excuse to try this project out :)
We've arrived at a very interesting point in the evolution of programming languages. For a lot of tasks there are several functionally interchangeable languages to choose from, so increasingly language choice is a matter of taste and style. Languages are developing the same kinds of brand identity that used to be the domain of cars and clothes.
