Here's another way to look at it: I've never, ever been in this forum (not attached to an article) until this issue. I didn't even know it existed. The people who use filters like 'like/dislike' or 'helpful/not helpful' are those who feel they don't have the time to read the full articles and need filters, and certainly don't have the time to post in forums like these. Yet this a very important audience, and the companies that have the money to find that out all feature social filtering as a fundamental component of their content.
When you look at the comments on the MacRumors redesign, there were a lot of people requesting that the voting return, and usually written in one sentence, not paragraphs like this
There's no question there's too much information. Some other rumor sites highlight major news in red to distinguish "New iPhone prototype photos confirmed" versus "Nokia appeals court decision in patent claims against Apple". People just don't have the time to filter everything themselves.
The question IMHO is not whether voting should be removed for the people who know how to use it and value it, but what are the voting criteria that are more helpful/relevant:
Helpful/not helpful (Amazon, Yelp)
Like only (Facebook, iTunes)
Like/Dislike (CNN, Reddit)
Views
Relevant/Not Relevant
Positive/negative (I can't think of any site that displays both the positive and negative, and the fact it's not really used anywhere else may be a factor)
Again, when every media site out there is rapidly adding social filtering to help the busiest people sort through the information, and companies like disqus and pluck are dedicated to providing that very service, it seems somewhat conservative/traditional to be removing it here, ironic since Apple is anything but (hmm, maybe not when it comes to social media...)
Anyway, the bottom line is I'm taking the time to write this as an investment in time lost as I find myself transitioning from reading every word of every article for the past ten years to now skimming the articles here, but not before now reading the article headlines at appleinsider.com first instead. I would switch back with filtering.
ps I guarantee, seriously guarantee, you will have more traffic in the comments section if people were allowed to filter by most 'likes'. There are some hilarious posts that capture the essence of the article beautifully, like The Daily Show would write, or those with incredible knowledge of the topic in general that provide valuable insight, but they're buried on 'Page 6'.
