I gather ideas for this blog from a wide range of sources, but these are my favourites:
You may have heard of this one already?
Just the best darned community-collated collection of links and commentary this side of the black stump.
The finest one-person blog on general trivia out there.
No Such Thing as a Fish
A podcast by the researchers behind the TV show QI. Endlessly amusing.
In Our Time
A long-running British radio programme (and now also a podcast) by the grandfatherly Melvyn Bragg.
Brewer’s Dictionary of Phrase and Fable
One of the best reference works for the professional browser.
