hi @jenn, I also follow storyfix.
I have learned the most from
Nathan Bransford, literary agent turned author http://blog.nathanbransford.com
Rachelle Gardner Literary agent http://www.rachellegardner.com
Oh, there are so many but these 3 have been the most helpful and informative, from writing, querying, pitching, publishing, and what agent really think.
but all the blogs I follow have been helpful in one way or another.
If anyones interested in the full list there’s one on my blog. http://scarletssanctum.blogspot.com/
