I'm finding it difficult to square your assertion that Reddit is "unique" in this respect with the assertion that it's the web that's "making marketing and distribution free". The only way that web marketing is "free" is if product awareness spreads between customers, or is pushed through the founders' personal contacts. Wouldn't this imply that we could expect this phenomenon - the initial user base being in some way close to the founders - to grow as the industry approaches the asymptotes you assert it is heading for?
