Apply a no-exceptions whitelist to your email and you'd have the same thing. Almost nobody does, this, though, and for good reason. This guy is absolutely right that Twitter is a clever design that folks would be wise to learn from. But Twitter doesn't so much eliminate the problem of spam as dodge it: most people still need a way for relative strangers to get through to them, but they have email for that, so Twitter doesn't need to solve that problem. If email ceased to exist, Twitter might find themselves pressured to reinvent it, and then spam would arrive right along with it. Similarly, if Twitter yielded to pressure to create a forum like this one, where relative strangers can contribute to discussions, trolls would arrive right along with that feature.
