I am supposed to research and read past posts to an online group once I join? Wait, what? Just kidding, that makes sense, actually. I just did not realize that it was internet RUDE to post a question without looking to see if it had already been answered. However, on sites where more interaction with current members is encouraged, I can see how this rule should be overlooked. For example, on MyFitnessPal.com, users can exist in friend groups while still being mostly anonymous. In order to create more friendships and therefore more interaction with the site, posting without looking back is probably better. Those who would be annoyed will not look and sort-of-new-users can share their recently gained knowledge with brand-new users.
