For a new startup, would you honestly recommend going with pyramid? And what about Django.. do you think it'll go faster to prototype and develop with pyramid?
Depending on what you're prototyping, it could very well be done faster with Django. Django provides a bunch of 'generic views' which can make tossing up lists of objects from the db very fast to get started with. Then usually you end up fully replacing it all later, but it gives you a good start.
If your app doesn't clearly fit into the sweet-spot's for Django, the argument will be less compelling. The pyramid code-base does have a lot of maturity behind it, it's not completely brand-new, so I don't think it'd be a problem to develop against it to be able to utilize its additional extension points.
add egg:WebError#evalerror into your pipeline. It isn't in the default Pyramid paster template, but, it was mentioned that it will probably be included in in the default Pyramid paster templates. http://goo.gl/EDqNo is a document I wrote regarding the transition of a Pylons 1.0 to Pyramid 1.0a1 application.
My views haven't changed since I answered this: http://stackoverflow.com/questions/48681/pros-cons-of-django...
