Even if Google was 100% unbiased politically, providing yet another major outlet for people who have no problem getting their message out already seems redundan

Even if Google was 100% unbiased politically, providing yet another major outlet for people who have no problem getting their message out already seems redundant, unless the point is just to reinforce existing power and influence. I don't expect them to promote any old blogger with an opinion (though I'd even prefer that to this), but giving a platform to marginal/dissident figures or organizations, from any part of the political spectrum, would at least serve some kind of interesting or useful purpose.
