I noticed the same. We don't have a precise underlying model without real unique identities for everyone. That's the rub - people want multiple identities, and don't always want to share their real one. Add to that multiple software systems, and it's messy. The tradeoff is a more reliable "less messy" world, but much less innovation. This doesn't mean that software requires less QA or design, just that it's a trade-off of two different modes of operating.
