I hate gaining self selling comments. Often, if I'm not feeling snarky at the outset, I do following reading them. So I wrestle using the urge to hit that delete button. I built a careless comment over a blog posting recently. I did not fully appreciate the impact of my text and regretted it afterward. I think from time to time you don't realize how public your comments are and that you should make certain you filter your opinions for public consumption.
