Checkout Stumble. Its not like Digg or anything else I’ve come across. I challenge anyone to demonstrate the kind of exploit you describe. It’s certainly not obvious. And I don’t think they deliberately designed it with that problem in mind but, accidentally, they’ve created a structure which is very difficult to subvert.

the vibe of all your articles is very negative and destructive … why bother? you raise some very valid points but please – be more positive. you make me feel like throwing my pc out the window

>>96% of my traffic (since Xmas) has come from websites and only a couple of % from search engines.

>>Also, I have to say, speaking as a serious researcher, that I don’t have much trouble finding what I’m looking for on the web

If you were looking for your own articles with Google, it sounds as if they may be difficult to find. With only a few % of your visitors coming from search engines, you illustrate the point perfectly. Since you have significant traffic, browsers must find your site useful or interesting.

With a few thousand unique visitors waiting for any story that makes to the Digg front page, the temptation is evident and the accounts created only for voting stories up are rampant.

While Google does not do it, the amount of hand-coding of search results that goes into Yahoo! and MSN might surprise the general public. Check out this one example of a Yahoo! search that they obviously do not hand code:

One inventive tool that Yahoo! does offer to fight this is called Mindset — allowing you to vary the search results between informative and commercial. Here is the same result through the Mindset shopping/information filter:
