I really don't see a problem with it at all. If all you're posting is a link, esp. with no commentary, then why make the user go to your web site just to click on that link and go to a second site. Start with the source if all you want to do is point. Why point at a picture of yourself pointing to something else? That seems like unnecessary cruft just for the sake of tradition. Not to mention it's probably more economical just in terms of server load - which makes it ever-so-slightly greener to do. The past is dead and gone. Get used to the shifting paradigm of shifting paradigms!
