I comment sparingly on posts because I'm loathe to seem a toady. I've seen some blogs where the same fellow comments on every post to the point of nausea. Sometimes I'll want to comment on a post, but I don't, because my comment will be lost among the high number of comments. Some bloggers can write "I went to lunch today" and get 62 comments. Others will sweat over a masterpiece of eloquence and wit, and not receive a single comment.
Reading maketh a full man, conference a ready man, and writing an exact man.
Keep on bloggin', dudes and dudettes.
