Think about the magazine section in your local supermarket. If you reach out with your eyes closed and grab the first magazine you touch, you are about as likely to get a group rates tabloid as you are a respected group rates journal.
Now imagine that your supermarket is so accommodating that they allow anyone who has an opinion on group rates, well informed or otherwise, to just stack their group rates articles, magazines or books in the store. Now if you reach out at random you are highly likely to get junk information on group rates and lots of it.
