Is there a doctor in the house?

I have a blogging disease. It includes two parts:

1. Post killer
2. Ignored comments

Now, I'm not too upset with this disease, although sometimes it is limiting and frustrating. Let's discuss each part:

1. Quite often, my comments will kill a post. Either I will have something brilliant to say (doubtful), or what I've said is so mundane, so ignorant, or perhaps so ridiculous that nobody can think of anything else to say. Of course, it could also be attributed to another symptom: commenting-after-the-discussion-has-closed.
2. Similar to the first part, this symptom happens frequently on blogs and posts that are deemed "intellectual" (see here, here, here, and here). Since I do not have a PhD in philosophy, law, education, history, language, women's studies, English, or...wait, I don't have a PhD. Okay, this makes sense now. I need a PhD in order for my comments to have a response. Another thing I seem to lack is a sense of humor. However, I'm good at bitter, so maybe that's wrong?

In my quest to fix this, I have found a cure: Stop trying to leave comments on blogs that don't go on and on about motherhood (which, in mine --and their--defense, are my favorite blogs. For some reason I just get them). So, if I choose to stay out of intellectual debates and quandaries, then perhaps my blogging disease will cease. But I can't stop. I'm addicted, I tell you! Addicted! Therefore, I will continue to allow this disease expose my weaknesses and humiliate me to no extent. Go figure.
