Stumped: over 5,100 new installs since yesterday and I don’t know why

This is fun, but I have no idea what’s going on. My inauguration countdown widget must have been featured in a directory or something, because installs started spiking at noon yesterday and it’s seen more than 5,100 installs since then. I can’t locate the impetus. They’re all through Clearspring, and most are marked in the stats as having come from the Google gallery, but Google reports fewer than 100.

I’m new at this—obviously, or I’d have seen to putting in some of my own tracking—so clues would be very welcome.
