Here's some for AOII - I looked up our biggest southern chapters, because I know they are all competitive and would most likely have up to date websites, then threw in Lehigh since my alum friend is their adviser and I knew it would be current.
One thing she found is that chapters are relying on Tumblr more than websites, she had a really hard time convincing the chapter that they should keep their website current since only "old people" go to websites. Harrumph.
