What do Commenters expect from Posters? YOU commented...you gave us your opinion...(sincerely, thank you for that)...but what are we supposed to do, then? Especially if it's a topic we are knowledgeable on.
It helps to know your audience...especially ones that are new or who tend to be defensive...but still...when you Comment...know that you are putting it out there...and that something might come back to you. Learn how to handle the come-backs without being too defensive...there is a reason you commented in the first place...once you've taken that first risk you might as well stay and enjoy the party. IMHO
