Ryan has written a great article about the information architecture of College Crunch, the site I am currently working on developing full time for him.
He breaks down each section we have created, as well as the reasonings behind it while also reminding others of the need to pre-plan their information architecture in a smart way.
The larger a website is meant to be, the more critical it is to get information architecture right. Otherwise, changes that don’t lend themselves to the original structure will take days, weeks, maybe even months to re-organize. The use of tags or other semantic indicators can be very helpful in matching together related information.
