Even though I am still considering leaving Bloglines as my readers of choice (the reasons are not the subject of this post, but are related with the fact that I feel it lacks a lot of features available now around the web) I can’t stop not noticing their new blog search, with the great fact that they are searching what people subscribe to which should mean that we’ll get less spammy results.
Since blogging and feeds tend to be more associated with individuals rather than organizations, Ask has also implemented a sophisticated name-recognition capability. Search for a name, and for active bloggers you see links to posts by and posts about the person. Another feature surfaces “top feeds” based on a combination of relevance to your query and popularity of blogs that match your query.
