Amazon, but you won't catch us kvetching about a little competition in the market place. In an attempt to do for indie writers what InstantAction has done for indie game developers, Barnes & Noble has just announced its intentions to open up a self-publishing portal this summer. We wouldn't say that the PubIt! name is the greatest of all time (for a variety of reasons, frankly), but the world's largest bookseller is hoping to expand its importance in the digital realm by giving wannabe authors the ability to upload and sell their material through B&N's website and eBookstore. Details on the compensation model (read: profit split) will be announced "in the coming weeks," but the real kicker here is this won't be limited to the Nook; pretty much any e-reader, tablet or PC will be able to tap in and make purchases, so the potential audience is quite large. Hit that source link if you want to be notified when invitations are going out, and given just how close we are to this mythical "summer" thing, we'd suggest you start putting pen to paper -- and fast.
