What do I give a crap about some sockpuppet content ghostwritten by a Fed -- since when am I reading the comments on Daily Kos, or some random dude's Twitter? Who cares what articles people vote on? I spend most of my online time reading an incrementally updated newsmagazine of my personal favorite writers on the planet via RSS.
Are you concerned about undue influence on public opinion? The only people being swayed or convinced by some sockpuppet campaign are those whose opinion is already made of shit. Do you really think that J. Random Congressman or Alfred E. Media Representative would be likely to have a sane, rational opinion on the issues of the day anyway? A couple dozen or hundred automated propaganda-bots are not likely to make his decisions even worse.
There's no reason to care about how the winners are picked. The cool thing about the Internet is that there's room for everyone, and that doesn't seem to be changing at all. That is the right system, and we're already there.
