It seems we’re having some sort of trouble displaying the custom header image for Zeal and Activity. I think that we have restored the header text. Sorry if anyone was alarmed by a blank Kubrick header. We’ll fix it as soon as possible; in the meantime, please pardon our dust.
UPDATE: This seems to have been a WordPress-wide problem affecting all embedded images. The crack team at WordPress.com got right on it, and we appear to be back to normal. Thanks, WordPress!
