Python for web - the next frontier (for me)

I just had a great conversation with Rob Eroh, VP of Product Development of Milo, over the phone tonight. He had some great insight on how Milo started, the work they put in, and the things entrepreneurs should think about when starting a consumer web start up. Along with being a great guy, Rob and I talked about the type of codebase that was behind Milo and the expertise I had. I am coding in mainly PHP (I used some Python in my VERY first project), while Milo is build mainly on Python. Rob has directed me to a Python framework called Flask, which he likes a lot. I have decided that maybe it is time for me to learn how to build both more scalable code, and code in something other than PHP. So, I have promised myself my next new project will be written in Python on top of the Flask framework. I am hoping there is not too much of a learning curve and there won't be too many (more than 3 lets say) just staying up learning it all. But, it will be a worthwhile experience that I am sure will be useful for me down the line. Also...if Rob is reading this, don't worry I did not forget to look into Hudson.
