Ok, something totally unexpected happened. Last saturday I was watching something on TV with my tablet on my lap, and someone I know asked a question about it on Twitter. I fired off a quick reply because I happened to know the answer:
@tombogman De huishoudster van de Sint, echtgenote van professor Van Den Uytleg,,,-- Maarten Schenk (@mschenk) November 17, 2012
And then inspiration struck me: there must be thousands of questions on Twitter that never get a reply.
