Comments: For the Vox Populi: A Comparison of How Some Blog Aggregation and RSS Search Tools Work


Very interesting post, and a good clarification of how different services work. We (Technorati) actually have the aggregate link counts in our databases, and we could show them if people think that this is an interesting statistic, but what we've found is that using it for ranking or other authority calculation is problematic, because it becomes a very easy thing to game - many links (e.g. a robot posting multiple times linking to your blog) may inflate your counts arbitrarily, and by definition, these counts will always increase, giving significant deference and near-gentrification to bloggers who have been around for a long time. I don't think that we really want that. Of course, no system is perfect, but we're trying to keep our authority rankings pretty relevant - thus the focus on links from the blog homepage making a difference in the rankings.

As soon as I get a chance I'll write more about this on my blog, but it will be interesting to hear what other people think about this practice, our goal is to be of service...
