I like this one. But I am prejudiced since I just started it today. It's rather simple at this time but I am just learning to set up a blog. Hope you all add it to your current reading lists. Thanks.
As far as handicapping and current/news information, the best one by far was Gary West's West Points on the Fort Worth Star-Telegram site. Unfortunately, he is no longer with that paper. This one is good for all-purpose racing info: www.courier-journal.com/racingblog.
