[Discuss] Rob Conery's critique of MySQL?

[Rich Braun]

For those of us lacking a 57-minute attention span to watch a full-length
talk, what's the gist of Rob Conery's argument?  For many, I suppose
PostgreSQL is a "default choice" but that isn't the case for most of the
open-source tools I've used in the past 10 years.  I'm now on a project for
which the default choice would have been Oracle, but the software architect
has chosen MySQL as a cost-saving alternative.

Why was this architect wrong?
