Halloween Book drawing winners

Congrats to Tena, who's won a copy of "Bitten by Moonlight," edited by JoSelle Vanderhooft (Zumaya Press, 2011) and Cat Rambo, who's won a copy of "Haunted Hearths and Sapphic Shades," edited by me (Lethe Press, 2008). Thanks for playing, everyone! :-)

Social media and the author

that being me, in this case.
A totally unscientific survey of my recent book giveaway and what proved most effective in getting the word out:
I got 23 entries in 3 days.
I promoted the giveaway on Facebook, Twitter, LJ, Dreamwidth, Red Room, Goodreads, Googleplus and several lists.
Facebook - 5 responses
LJ - 6 responses
Dreamwidth - 1 response
Twitter - 4 signal boosts but no responses directly on Twitter (may have driven traffic to LJ instead)
Mailing lists - 10 responses
Googleplus, Goodreads, Red Room - nada

Not too surprising. I don't find the blog functions on Googleplus, Goodreads or Red Room to be particularly useful or active. Dreamwidth is also pretty traffic-light for me, which is why I keep LJ around. Twitter seems to do best as a wag to get the word out quickly, while Facebook and lists are much more interactive.
Anyone else have better luck with the other sites than I did?
