I normally read all the posts, especially if I feel compelled to comment.
One of my pet peeves is people who make a comment not bothering to read what comes before. (I hope that no one takes this comment the wrong way.) And, yes, I would hope that what I had to say was as important as the next one.
I have just recently started commenting on quilts in the picture category; so, might just post at the end, without reading all the posts. But, I am here so often, too, that pages are not many when I post.
