TWO FUNDAMENTAL QUESTIONS ABOUT BLOGGING

Someone has suggested that there are people in the blogging world who link to others merely to get links in return. I link to a lot of sources. Other weblogs I read have a link in almost every post. Is there some written or unwritten rule I’m breaking?
Second, I’ve been accused of shouting. Apparently, the fact that the titles of my posts are in all caps gives some the impression that I’m shouting as one might in a chat room. Never was that my intent. I’ve composed compound documents all my life and some of them have all caps in key headings or section breaks. Is that shouting? Again, what are the rules of the road?
