A spam presented the neologism of the day here.

Somebot claimed to be "a wideo from Nigeria".

Wideo, n, botspeak variant spelling of (likely) "widow". Flaggable as spam.

Those who read my stuff at bsdly.blogspot.com (ie the tracked site) will hopefully be pleased with the new look which I think offers better readability.

New stuff and most of the useful older things will still be available without trackers at nxdomain.no/~peter/blogp..., of course.
