First things first. I think Tumblr is great... Especially for the price (free!). I moved over an old dormant domain (TechOnABudget) to it from a self-hosted WordPress site and am using it for a new domain (ComicsViews).
However, like Twitter, Tumblr goes over capacity now and then. You get the fail message seen in the screenshot here. The problem is that the error message has no personality. Since this is going to happen from time to time, I think Tumblr needs a fail whale type mascot for its over capacity message. Recommendations???
