Because such “commercials” are not inconsistent with Quora’s missions:
- publicly: to increase the world’s knowledge
- publicly, when the Founders let their mind wander: to serve as a cache/substitute for Google
- speculatively: to serve as a testbed for from sweet, sweet AI
They’re not very sociable, I admit. Even though I’ve done it myself, and recently at that. But, after all—all together now:
Quora is a Q&A site, not a social site.
