Generally speaking, I refrain from reading 'comments' on the web. People comment on everything. Sadly, the majority of comments are borderline ridiculous. The random times that I actually read comments, I usually come away wondering if the people that wrote them suffer from mental retardation.
If future generations were to sum up our society based on a study of 'comments' on the web, I'm fairly certain their summation would be, and let me phrase this in a currently fashionable Internet phrase, "Fail."
