It's just alpha.  Things still change fast enough that occasionally an
upgrade breaks stuff.  Persistence is still very iffy, someone's been doing
work on magma as a backend lately, but it's too new to say how stable that
is.  Security is bare bones, it works, but you'll end up adding and removing
users in a Squeak workspace.  It's fairly easy to break an environment page
and hose a site with invalid html, forcing you to dig up the kernel in a
workspace and try and fix the page you broke.  Works ok if you're a
developer, but if you give it to a user, they'll find a way to break it
rather quick, at least that's been my experience.  Don't get me wrong, I
love Pier, it's going to be my development platform of choice, it's just not
totally ready yet, we need a larger community finding and fixing bugs and
stabilizing it.
