I've tried very hard to assemble a list of my favorites for 2006, but it's turned out to be harder than I thought, this is my best effort:
Union Dues series - it's hard to single out one as better than the others
A Single Shadow - a fun character piece
Paradox & Greenblatt, Attorneys at Law - I'm a sucker for a good Time Travel story
Observations from the City of Angels - I loved the way this one was told, it's make a great film
Head of State - The Reading on this one was awesome
I look Forward to Remembering You - more time travel!
Creature for Hire - Laugh out Loud funny throughout
Shadowboxer - awesome mood piece
Chuckles Mulrooney, Attorney for the Damned - How can you not love a story with a title like this
Tk'Tk'Tk - not one of the best, but worthwhile
Are You Ready For the End of the World? - surely Paul S Jenkins deserves more appearences here
Connie, Maybe
Hero
I made a list of those I didn't like, which turned out to be surprisingly short:
The Dinner Game - bit of a Jar of Tang story
Margin of Error - All this author's storys seem to be based on the idea
nonotech is bad, and babies are good!
barnaby in Exile - bleh, sweeter than candyfloss and about as much
substance
The Capo of Darkness - bit heavy-handed with its preaching
The King's Tail
Down Memory Lane - way too sentimental and depressing for me.
Seventy-Five Years - this is practically a script, it's so short on prose
My Friend is a Lesbian Zombie - this is a title with potential :p, sadly it's not lived up to
