My comments sometimes outnumber my "thumbs". Why? Thumbs inspire confidence. Isn't nice to have your confidence inspired? Well, do unto others, no? But even if you're a dick, thumb anyway. Karl Rove would. It's free, fast, & effortless self-publicity in the left sidebar on the Open Salon homepage, the sidebar labeled 'Activity Feed' for good reason, because it showcases activities, like thumbing. Observe:
I thumb at the top; and if I get to the bottom, I sometimes comment; but not always, because commenting takes time, time I could be thumbing my way toward another post I dig, read, & finish. Or find nothing I dig, give up, and reread Skip Williamson's Art & Life--my favorite blog on the Internet.
