Ask HN: Web app microtransaction vs. subscription?
Instead of a monthly subscription, anyone can use the site but advance functions require credits/micropayments. For example, Basecamp - if you add more people its $2 per month per person. if you like to add 50mb or 100mb add $2 or $4 month. Would this work? This has happened in the MMO space. whats stopping it from working in the web app space?
