My question too. I backed Light Table with the hope they would hit the Python milestone.
I won't back them based on a maybe. We'll talk again when python support becomes more than a teaser :)
What I mean is, say the project had been set at 300k and python was one of the base supported languages. That would actually be no different than it is now, except that now the software itself is already guaranteed(1).
Also, the python inclusion is certainly on the roadmap if it's mentioned before the project has been funded, right? So if you back it, then you're still probably backing a(n eventually) python-speaking platform.
1 - [Edit]: Well, "guaranteed", no. Funded, yes.
