I have an important message: this is a falsehood, most likely orchestrated by the Django marketing machine.
Pylons *DOES NOT* lack a pony -- Pylons (actually Paste) has included a pony (paste.pony) out of the box for 3 years, since the Pylons 0.8.1 release. Here's Ben Bangert demoing said pony at a Google tech talk over 2 years ago.
Typical Django and their NIH attitude -- instead of checking if Ian Bicking did it first, they just went off and made their own pony. That's fine though, we don't mind the Django pony. However the lies about Pylons must stop immediately. I demand a retraction and an apology from the Django camp.
