I think we were probably too old for this on our 18th birthdays...

I won't be offended if I make a comment on someone's post and the author never comments back...but it does give me pause when am one of many commenters, and my comment is ignored and everyone else's gets a mention. Usually, it's because I am swimming against the current of what the poster wants the comments to say...if all you want is a friends list full of sycophants, why bother posting anything worth debating?
