I think that two important things to remember about posting comments are that you need to be polite and you should actually say something of substance. No one wants to read comments that are full of wow your so right, and cool. And no one wants to read comments with a bunch of insults. People have to remember that just because you cant see the person, doesnt mean that they dont have feelings. no one would blog anymore if that was all that anyone ever said.
It was fun commenting on other peoples blogs. at first i was nervous and wasnt really sure what to say, but the more comments i made the easier it became. i chose to comment on an outside blog about global warming and another one about gas prices because these are extremely important issues today that i felt like i could say something worthy of being posted. i also chose them because i did not agree with them, so i got to put some of those commenting rules to use!
