@glitterbag,
Le sigh? Are you that frustrated?
On a serious note, Jeffrey hit the closest than anyone here.
Congress, in the year of 1996 established that web sites publishing 3rd party content are not liable in the manner than media corporates, such as newspapers who are liable for publishing submissions from its consumers. That is why CNN blogs and other such services are available for opinion of readers to be put out there without liability.
In such manner, A2k is just a blog, with a marketing gimmick, that you just covered regarding the "expert" motto, but with disclaimers in their policy section. Educating each other, and sharing of information, and people deciding what is true and what is not, is what Internet is all about. No different for A2k.
