I feel that if I start this comment with a salutation, it may seem like a cliche. So I'll just... talk I guess (it might seem a bit robotic, lol).
Comments are little "notice me" post-its that draw attention to one's blog. And it all depends on you to use it well.
I agree with @maryfavour, once you don't like or understand a post and you have no meaningful comment, Biko, just jump and pass. It's not by force, there is no knife at your throat to comment so don't half-ass it.
You can disagree with an author, but please be intelligent about it.
You've done well @ogochukwu
kudos
Quick question: are those names real? @punkman and @Theblahblahblah.
