Nominations are open for the Nebula awards (if you're an SFWA member) and the Hugo awards (if you're a WSFS member -- attended worldcon in 2010 or are attending/supporting 2011). The former close in mid-February, the latter through March 26th (nomination forms here).
I feel the need to mention this because some of you may be tempted to nominate a short story of mine which is in fact not eligible.
The short story is "Bit Rot", published in Jonathan Strahan's anthology Engineering Infinity. It's an interstitial between "Saturn's Children" and my forthcoming (in 2013) sequel "Neptune's Brood". The reason it's not eligible is that the official publication date is January 3rd, 2011. However, Amazon have gotten this wrong and are listing it as December 28th, 2010.
So don't bother voting for it.
(Other than that, my only eligible works in 2010 are novels: "The Trade of Queens" and "The Fuller Memorandum".)
