When I told a Clarion mentor, Michael Armstrong, that I was debating on whether to submit a short story to Asimovs or the new Baen's Universe magazine, he shared a caution with me about Baen Books.
He had some contract disagreements with Baen and advised that people be very cautious in working with Baen Books. He also filed a grievance with SFWA over the matter.
For those interested, Michael's bio is at http://ebooks.wildsidepress.com/servlet/mw;jsessionid=P7Zrb0JdbjbSZhCXs…
Asimovs looks better and better. Must get back to writing now.
