It's amazing how many new words are being created or repurposed lately. Take the term "indie." A few months ago an "indie" author was anyone who published with an independent or small press. Now many are using it to describe any person who self-publishes.
Here's another term for the self-publisher I picked up this morning. It's my favorite new portmanteau -- "nongatekept author."
I suppose then that a "traditional author" publishing with a "legacy publisher" might be a "gatekept author," which sounds rather ugly, doesn't it? Like a shackled prisoner who's locked up for 18-24 months, forced to sign noncompete clauses, and when they're finally let out, have to perform like some sort of zoo animal in exchange for peanuts.
Let me know if you come across any others.
