Great article. I think the other angle that should be mentioned is revenue versus expense. How much is it costing to grow? When the 'growth' stops will the remaining future income be profitable? Our business grew aggressively and we spent aggressively, but the fundamental scalability of the business was more 'traditional', in that the expenses matched the revenue growth, so the overall margins were low to non-existent. I can assure you in that type of business you will always be scraping by, if surviving at all.
