It is important to note. This is not truly anarchistic.
It is based upon shares, stakes, in a company.
Those with more stakes can have more power to vote up or down. They can essentially lift you into the limelight, or drop you into the dregs. This also depends a lot on how whichever tool/site (I like to call them "windows") for viewing the blockchain you are viewing. It could be possible to make a "window" that ordered posts in a completely different way.
It is important to note this is not really anarchistic. It is more like we are all investing in a decentralized corporation as stake/share holders, and one of the desired/stated goals of the corporation is anti-censorship. In terms of the blockchain this is true, yet different "windows" into the blockchain could indeed censor information from their view. This is not necessarily a bad thing. People who want absolutely no NSFW feeds could use a "window" designed for them, and those who love NSFW could have a window where it is brazen and unfiltered and perhaps even intentionally highlighted.
So censorship of the blockchain does not exist. It does however exist on a "window" by window basis, and the up vote/down vote with power based upon shares/stakes can in fact act as a form of censorship.
Yet when we think about it there are some forms of censorship most people do endorse. Censoring the plagiarist, spam, and abusive. Some of those terms being completely subjective.
I agree with you 100%, I have repeatedly predicted Steem's success will stand and fall with the interfaces and analytics tools and filters that will be developed and used a gif from the Zion approach scene in "Matrix Revolution" each time:
I'd be much less concerned if the rep system were simply a metric computed by the interface, a short analysis calculated by summing up- and downvotes somehow. But lo and behold, https://steemd.com/@dwinblood says there is a new cell in the database:

And it did not even seem to require a hardfork, unlike the update to get rid of the liquidity reward bug using.
Other interfaces will not have such luxuries.
