The problem with using those systems (an agency I freelance for uses basecamp) is that since they are servered on the basecamp servers it takes forever. I have highspeed comcast internet out of my home office and it takes me literally hours of time waiting for the site to load and upload new features. Whereas when I use my wordpress site I can upload fast and have no trouble exchanging information with newspapers or radio stations. I decided to use a members plugin to privatize my "project wordpress site" and I'm using the "more fields" plugin to add specific areas to the write panel.

Wordpress is smooth and with enough knowledge you can create anything you want from it. Anyone who says that it "can't be used" for "shouldn't be" used or "isn't made for" doesn't understand what Wordpress can do whatsoever.
