Mark Ramm goes into a bit of detail over the recent speculation of Merging TurboGears and Pylons? I had a comment about this on the Pylons mailing list as well. Those of us using Python to develop webapps have a great variety of tools to work with.
It’s worth noting that I (and many others) like the style/feel of TurboGears apps (which is to say CherryPy-style dispatch by default and Genshi templates). Though TurboGears and Pylons currently share a good bit of code and will undoubtedly share more, it’s the style/feel thing that represents the difference between the two frameworks that may not resolve itself. (Of course, TG apps will be able to use Routes+Mako if desired, and Pylons apps can use CherryPy/RhubarbTart+Genshi if desired… those just won’t be out of the box defaults…)
It sounds like the two cores can be integrated and users can download different runtime profiles. Similar to Dojo.
