In commenting on Yahoo News search Dave Winer suggests "Blogs don't belong in the margin, they belong in the main results."
Looking through a search presents some problems with this idea. An average search shows several copies of results of posts from this blog repeated on several other spamertising blogs. This means that to decide which blogs should be included an editorial decision needs to be made on the part of the information provider. An offhand suggestion says perhaps you go to the first copy of the post as authoritative. However this will just cause the illegitimate sites to backdate their posts to appear to be the original.
Rapidly this becomes an area where the authority of the editor becomes important. With the New York Times for example I'm able to judge from many volumes of history what I think of their editorial policies. How do we learn to apply that same judgement to collections of personal publications?
