A suggestion for Giles would be to link back to the HN conversation of each link. I think its not the foreign content that people find useful on HN, its the conversation around it. (fjabre also pointed this fact out.) Especially considering that the majority of content on HN derives from a few websites - something which I think should be a goal to change. Personally, I love the fringe stuff and being introduced to new blogs that I don't normally come across. Through these fringe postings, I have found some very interesting people that I now follow. Alternative insights are awesome.
