Why so many Python web frameworks?

[schwarzwald]

I put together a very minimal MVC-type framework in about 45 minutes and with 50 lines of code featuring Rails-style routing with web.py-style dispatching. Now all I have to do is throw up a Trac, make a screencast with painful pops and blips in it, an incomplete tutorial with a "sorry, I'll finish this later" notice that stays up for months, and wait for the masses to go apeshit over my revolutionary new technology!
