I like to try to help my friends when they post comments with questions on my wall. However, one came through lately that asked about how to jailbreak iphone 3g and I had no idea how to reply. So I sent info at the link there as I ran across the content via a Google search. My friend thanked my and said it helped a ton. So I went on to help others, since that worked fine. Facebook keeps changing so much, but at least friends can still interact there. If they'd just watch their ads, and keep them to a minimum now.
