DHH’s post about the Rails 2.0 is incredibly well written. It is almost as he is showing off a unknown past as a PR agent when he talks about Rails not supporting commercial databases out of the box:
But that doesn’t mean the commercial databases are left out in the cold. Rather, they’ve now been set free to have an independent release schedule from the main Rails distribution.
This sort of well formulated marketing has been known to render some sour remarks from the rest of the open source web framework world. My belief is though that when they ask themselves “Why are people so attracted to Rails, my framework of choice is just as good or even better”, sentences like the one above are probably a large part of the answer.
