Who gives a toss about genealogists?
Aside from the obvious point that people alive in 2011 leave a massively greater document footprint than people alive in 1911, so the idea that the census data will be all that provides information to your descendants in 2111 is faintly preposterous, why is the government funding something for the benefit of bores? The man who tells you that he's looked up his second cousins great grandfather in the census of whenever is a man you don't want to sit next to at lunch, and the government should no more concern itself about boring people and their boring hobbies with regard to census than it should underwrite model railways, orchid growing or geo-cacheing. Other people's hobbies are their concern, and if they're boring to me, well, at least they're enjoying it. But the idea that I should waste my time filling in a form for the benefit of bores yet to be born is laughable. The census has many uses and to me, the basic demographic information about me isn't interesting enough (or private enough) that I'm going to get worked up about it. But if the benefits is about Family Tree Bore Monthly readers, well, count me out.
