I think it was ridiculous that they made "Warp 10" some transcendental state where you're everywhere at once...as if they somehow "knew" that when they were creating the warp speed scale. They've never substantively explained why the jump from warp 9 (which they zoom around at all the time!) to warp 10 should create such a leap. Easy hook for a story, but makes no sense otherwise. And it gave us Paris and Janeway and lizard babies. Enough said!
