Just read a great post by webstractions that I would like to share with you guys. He comes up with a very interesting concept that seems to provide much more logical approach to the new indexing filtering method that Yahoo is deploying. WebStractions presented several alternatives. One of them is the creation of a new tag such has that I presume would wrap around the content that you wish not to get indexed. However, the most interesting idea was the usage of the old REL attribute (Relation) to dictate the purpose and origin of a given content. Could agree more with WebStractions, if it's not original content, it quite simply shouldn't be indexed as if it were. I still that Yahoo is leading the way, and it’s much better having this tool then nothing to work with, using a CSS class to filter our content is a rather dubious decision., would certainly be very interested to know the reasons behind this choice. WebStractions Yahoo's Robots-NoContent Another shade of NoFollow
