You're interesting.
I just read your post: Why is writing a comment on someone else's post so difficult? You have a breezy, perky, conversational style that "reads" fast. So I'm puzzled as to why someone like you who seems to be a decent writer would have any trouble generating thoughtful comments by the boatload. Perhaps the subject of a future post? :)
Thanks for the comment, I find myself with those words most of the time when I get around to replying to someone, or thanks for the content....most of the time I hit backspace, and leave the conversation...surely there's something more...more...I can say!
It could indeed be a great theme for another post, another to add to my list!
