I really like the idea of it if you can get critical mass. One concern I'd have is: given that people's livelihoods are often on the line, how do you keep it from devolving into Quora marketer-speak over time?
Thanks! I think there will be a similar challenge here, but we have community moderators (as of launch) and pretty strict rules around self-promotion. Example: some vendors (tool makers) wanted to write Decisions about their own product, but we explained why that's not helpful to developers and they understood. In many ways HN is really good at this, so the hope is that we can let the community moderate itself which seems like less of a thing on sites like Quora.
