Personally I think esoteric pronouns like "ve" are a silly idea that won't catch on, but I like the idea of using "they" as a gender neutral way to refer to one or more people.
It's a straightforward expansion of the current usage: as a gender neutral way to refer to two or more people.
My problem with "they" is that it's overloading the plural pronoun and using it like a singular. This can cause confusion, for example, it makes the comment we're discussing a bit hard to read when in one sentence "they" means Manning and in the next sentence "they" means the government.
