Seattlepilot, i believe there are and were some beta testers. Also a small-scale beta test cannot uncover all the bugs, especially those arising from a heavy server load. I believe this is why it is currently labeled as having a "24 hour testing period".
On the topic of critique, the only issues I have are the lack of drop-down menus, load factor not showing on quick stats, and some tables being improperly placed.
Tables I can live with, and you have already talked about the load factor. For drop-down menus, I understand it has had some bugs previously, but here is what I suggest:
-Keep the current
system-Make it so that mousing-over a heading will make its subheadings appear
For example:
I mouse over "Operations" - the options for "Create Route", "Edit Route", etc show up.
As the previous system only gave the option for a drop-down menu, this works better because those whose browsers do not support the menu can continue to do what is necessary now - click on the heading and then click on an option.
Other than these issues, the new look for AM seems to be much like the new Facebook. Its evolutionary and introduces some good features, but some things become harder or more complicated to access. Over time, people will get used it. I have...pretty much

Same deal with vista

Thanks and great job with the new look!
edit: one more suggestion - with all the links on the site anyway, could you please make the load factor (on each route) clickable so it takes you to the edit route page? This would make editing more efficient.
