I read most of the articles and just skimmed a few. I like that one of the sources noted that the comments should be concise and also help promote or even sustain a conversation. Of course, I appreciate the fact that criticisms should be constructive, too.
I did notice that one of the blogs discuss responding to comments. I have been getting some comments on my blog and I have never responded to them. So, I am going to make an effort to do that. It is like having a visitor in your home, at least a pleasant "thank you for stopping by" should be given!
I spent some time reading peoples blogs and made my comments on postings and pictures. It is fun to see other peoples avatars, ideas, thoughts.
There are a few blogs I follow personally. The reason I follow them is because they are people I know. http://www.i-get-to.blogspot.com/The women are witty, smart, and funny. I enjoy the smile they give me when I read their blog. I also follow the Katy Blog from the Chron.com website- it just keeps me up to date on the hot topics that are being talked about in my community. http://feeds.chron.com/houstonchronicle/insidekaty
