Comments.
Due to the large volume of comment spam I’ve been inundated with I have disable all comments. It’s not that many people commented on my posts but I had hopes that I could leave it open in case anyone wanted to share an opinion. Unfortunately, like many things related to the Internet, the spammers have ruined it. I hope some day to turn commenting back on, but it won’t happen until I install Captcha or some other form of “human” validation.
