I've been putting off publishing my review of Feed Wrangler. It was late to the game and had the most ground to make up. Believe it or not, I don't like to write negative reviews.
Today, Feed Wrangler bridged a major gap. Feed Wrangler OPML Import will now automatically create "Smart Streams" from Google Reader feed groups.
If you are already using Feed Wrangler, there's no need to delete and start over. Running another import of the Google OPML (XML) file will automatically create the new smart streams. It is a bit slow, so go enjoy a nice beverage while it's working.
