When I was applying, I considered bad program websites to be a bit of a red flag. However, oftentimes the people in the department don't have a ton to do with it. There are tech people, sometimes not incredibly familiar with pathology, who have control of design and function. The larger programs usually have the best websites, as they specifically have people in charge of the departmental website.
I thought some of the better websites were Iowa, MGH, Utah. A good departmental website says a lot. Michigan's has gotten better.
In regards to the seeming lack of desire by programs to send out information, usually there is a secretary or someone called "residency program coordinator" or something like that who is in charge of coordinating all things residency - receiving applications, sending out letters, all that. They are usually the best people to ask. However, most programs will send out information packets once you apply and they invite you to interview. Of course, if you are wanting the information to decide whether or not to apply, that doesn't help much. The amount of info you receive is as little as a single page letter inviting you to interview and inviting you to call or visit the website, or as much as the entire departmental handbook, list of faculty, promotional brochure, description of rotations, etc. Some go all out. I think it says a lot if a program spends time and effort to recruit residents. Some don't need to but still do anyway.
