Who wouldn’t enjoy Rand (or for that matter, any SEM professional) posting a [series of myspace-esque self portraits](http://www.seomoz.org/blog/the-emotions-that-make-us-link)?
Tiny problem though… I’d *love* to give feedback on the posts. There’s even a mechanism for doing so with the little “Do you like this post? Yes No” links in the feed. Unfortunately, clicking them turns up this result:
So is the feedback mechanism’s goal to get people to sign up? Or is it to get feedback on the posts? Perhaps you’d only want to publicly display the feedback from signed in visitors but I can’t imagine a reason not to still collect the feedback from other visitors.
A minor point to be sure, but a good opportunity to think about what purpose the different features of your web site are intended to serve. Are those features optimized for that purpose?
