I have got an assignment to check http://browsershots.org about its use in browser compatability testing.
Before operationalize i want to get some feedback here about this site. If i get some points on its usefulness and drawbacks it would be helpful.
I think that you might get more answers if you make your question more specific. Can you supply more information about your test parameters? What has your research told you about browsershots so far?
People will be more likely to offer information when you demonstrate you have done some background work yourself and you are specific about your target.
