For the same reason my bio on Quora topics promotes Quora Base Camp.
The studious lack of onboarding on Quora has been a long-running problem, and there have been tens of attempts by its users over the years to remedy it with their own guides. The problem has been that none of those attempts have gathered critical mass of visibility: the wheel keeps getting reinvented, and noone much gets to go on a ride on it.
Jennifer Edeburn, whom I count as a friend, had a genius idea when she embarked on her own attempt to write a guide for readers: viral marketing. Using our bios as walking billboards, to guide new (and not so new) users to help about Quora.
I thought it a brilliant idea, and I went one better when it went live. Necrologue, for better or worse, has a readership; and its footer is now a walking billboard for Quora Base Camp too.
