Although the common courtesy is to leave comments when visiting someone's MyBloggers page, and in spite of the fact that I enjoy very much receiving comments on my own page, I really leave them. I might visit and read some eight to ten posts at one sitting and leave one comment among them all. Terrible, I know. I would say more, but at some point my comments seem so trite and the little smileys so overused. So, I read, I smile and left click the next link with the same eager anticipation as always.
Fortunately, there's a little number next to the button called "Post Reads" that, when clicked, tells people I've been there. Since I rarely browse MyBloggers without signing in first, somehow you'll know I've been there. Perhaps that is "comment" enough. After all, if I didn't think what you write is interesting, I wouldn't have bothered to check it out.
Oh, and for the record, I DO allow the "interestingness" of an avatar to become a determining factor as to whether or not I click sometimes.
Very shoddy MyBloggersness, I must admit, but such is the nature of the beast.
Until later, my browsing reader, take care and blog like you mean it.
