For at least a year, links to Quora and Scribd have been considered, by me, to be non-existent. Every experience with them in the preceding six months had been awful, so I refuse to interact with them again (at least, until I hear how they fixed things).
Quora is casual fun. Like Reddit with text. Ephemeral.
(I am told by Quora investors that they really didn't try for the inane comparisons to Wikipedia, but that this was made up by the press; much as the comparisons between Wikipedia and Knol were. [I am a long-time Wikipedia press volunteer and watched that last one being made up out of nothing.])
