>While Python has a healthy web dev ecosystem, Ruby's feels much larger to me.
What is there in, say, rails that would not be available for django?

The difference is in the size of the ecosystem as a whole. The Ruby web dev world appears to have more (or more visible) participants. Which affects things like Stack Overflow, web-specific packages on Github, blog posts, etc.
It's not an order-of-magnitude difference, as far as I can tell. But still significant.
These things would make a huge difference to productivity if one platform had more (and better) of these things, but I haven't noticed that to be the case.
I much prefer Python/Django, but when I get stuck, it always lasts longer.
