As far as authors on Escape Pod in the last year, only Tim Pratt and Eugie Foster. Which is a bit weird, because I don't get excited about Eugie Foster on Podcastle, but I do for Escape Pod. I don't know what it is, maybe "When Shakko Did Not Lie" ruined her on Podcastle for me, but I just don't get as excited about her for pure Fantasy things.
Tim Pratt I love in any setting though.
As far as the other podcasts, Tina Connolly is getting to be a big favorite, and I was pretty excited to see Nick Mamatas on Podcastle (he was on Pseudopod last year).
But I think a lot of the best stories come from authors who aren't pseudo-regulars on the Pods, and some of whom I've never heard of before.
