I'm not entirely convinced by the arguments here. I think I'm more inclined to think this is a good idea because it does remind me of companies that partition their websites into shards for "personal", "small business", and "large business", because their sales force is divided into these categories. This is absolutely infuriating to navigate. I know what I want to buy: let me look at what you have to offer and let me buy it without having to care about how you structure your sales force.
