While e-mail usercount is not evenly distributed across many servers, the fact that it's open an interoperable gives you several things: - you can use whatever client/server you want (or host your own) - you can still communicate with your friends if they're on another server - servers are run by separate entities in politically distinct regions None of these things depend on there being a uniform spread of users across servers.
