Hi - this is my first post here. I've installed Drupal on two sites and will install it for a third.
http://www.saveourcommunity.us -- an actual site
http://www.riceball.com/drupal -- my personal site (pretty dead)
and I intend to implement the following site with Drupal:
http://www.riceball.com/montebelloashiya.org/
with this layout (warning - fugly first draft here):

Now, onto my comments.
About me: I'm just a guy installing and customizing Drupal. I know PHP well, and have programmed for a long time. And in case you're wondering: yes, I'm going to write some modules if I continue to use the software.
Things I like about Drupal: the extensible plug-in architecture; the built-in features you get with install, especially the navigation hierarchy; the taxonomies; and active developer community. I think Drupal is awesome.
Things I dislike about Drupal: not a great fit for the last project listed above; weak support for "CMS"ey "brochure sites"; most of the layouts.
I will start with the layout. I just don't like the three column PHP Nuke style layout. To deal with this, I'm using phptemplate to implement the SOC pages. It's got it's qualities, the main one being that I don't need to learn that much about the templating system. Still, the three column layout is pretty much wired into Drupal.
