We have gotten a fair amount of "Comment Spam" lately. Comment Spam is where an anonymous person posts a link to their website as a comment on your blog where the comment has absolutely no relevance to the article. They do this to help their "Google Score". The number of times other people link to your website increases your Google Score and gives your site a greater likelihood that it will show up at the top of a search listing.
As such, we will be moderating all comments from now on. Keep commenting, but there may be a delay from when you post the comment to when it actually shows up.
Life dictates that a few bad apples spoil it for the rest of the tree.
