I am a huge proponent of WP, have been using it for about a year or two on my personal sites.
I am now tasked with setting up blogs for the newspaper I work for and need to know if WP can handle a high traffic site? I am pretty sure it can, but need to ensure the highers up that it can. They are sold on MT as other newspaper sites are using it, but I am fighting for WP.
If you have some examples of high traffic sites using WP please pass them along so I can show the guys upstairs. And if possible, note how much daily traffic these sites get.
I need to make my push Monday morning, but if I can get enough supporting evidence ASAP I can show our approval guy and he will fight the rest of the battle for me while I instal and get WP up and running...
