I've been creating webcomics since 1998. During that time, I've seen the rise of the Livejournal, blogs, forums, guestbooks and chat/tagboards (I had a Livejournal BEFORE they became popular). I've also heard many concerns coming from other webcartoonists about feedback. Instant feedback and detailed feedback. For the budding web cartoonist, this seems the main priority (second only to begging for donations, but that's another rant). Of course, everyone WANTS feedback. It's nice to know that when you're 'speaking', someone is 'listening'.
