Interesting isn't the word I'd use, but I understand what you mean. I really hope that a third party will start to grow. Whilst it may have benefits, I think the two-party-system feeds a lot into the "with me or against me" concept.
Third parties don’t thrive in countries with first-past-the-post voting and without a tradition of coalition-making. In order for the USA to reach a point where it could have more than a two-party system, it would have to completely remake its governmental structure, and “very interesting” is an appropriate euphemism for what things would be like if it ever came to that.
