Hi Jim,
I'm settled on sticking with PostgreSQL since MySQL is just too
incompatible with my needs and desires. I just wanted to be
open-minded to some of the MySQL advocacy I've heard.
My project is essentially a CMS, but there are features that are
commonly found in social networking sites like MySpace and CampusHook.
I prefer to call it a web-based BBS inspired by my Citadel days that
borrows features from social networking sites and multi-user blog
sites (think Slashdot, not LiveJournal or Blogger).
I don't anticipate the kind of usage that a site like MySpace gets;
but should users really go for the social networking features, and
start hammering away at profiles with comments and updates; I'd like
to know that the database can survive.

/. is also essentially read-only, or fairly close to it. The only sites
I'm aware of that have gotten MySQL to scale in a more write-heavy
environment are only able to do so by hand-crafting a clustering
solution of some kind, so that not everything is in the same server.
Livejournal is an example of this.
Why would a CMS have that high an update rate anyway? I'd think it would
only be somewhere between 10% and 25% DML...
