The asymmetry that, it seems, has crept into modern life is that the business you describe will not attract investors, and (because the Internet has flattened the marketplace geographically) the heavy investor-backed company doing what you do 90% as well at 300% the convenience will eventually put you out of business.
Sure, if they have 300% the convenience. But I am pretty sure I will have more convenience. I'll have a Matrix server and website where customers, including their employees, can ask me questions. I'm pretty sure it will be maximally convenient for senior developers or a CTO helping to make the purchase if interns never ask them questions about my software.
