Or perhaps not so odd...
When I logged in to post, I saw that blogger has enabled automatic spam detection, which explains the first mystery.
A spam comment appeared in my e-mail, so I immediately logged in to the offending post to remove it, only to find that the comment wasn't there. It appears I receive spam comments by e-mail, but blogger removes them for me. Thanks, blogger!
The other little oddity was that I was at the Moo website. Moo recognized that I was from New Zealand, and invited me to click through to the site for my closest Moo retailer. This, it turned out, involved redirecting me from the US site to the UK version. Huh? Last time I looked, the US was closer, or has the world rearranged itself while I slept?
