The main thing for me is it should be "personal." Posts are one-on-one communication, whether others like/dislike a post, it's really a conversation from a responder to the original poster and an opportunity to learn from/about "that" person and your relationship with them. I won't put URLs in Candybear's posts or stop in AAAAA's, for example :-)

I try to communicate what's in my heart and mind to the person who orginally posted. Rainbowzz wants to know my opinion now, you other lot are welcome to it but it's got an angle to it, it's directed to Rainbowzz so it's like an HDTV, depends on the angle you're sitting at as to whether you'll have the best view.
