It varied. I always posted to my LJ and to my personal website and would post to other LJ Comms depending on the particular fandom/pairing.
Mostly I would only post the actual story to one place on LJ and that was usually my LJ. The other LJ comms I posted to would just be the story header with a link to the actual story. If the story was longer than one LJ post could handle, then I'd post the story to my website and all the LJ posts would link to it.
Occasionally a particular comm or fest had rules of their own whereby the actual story had to be posted to the relevant comm, in which case I would do so and link all my header posts to that comm. I did still post the story to my own website.
I did also post to an NCIS fanfiction site for a while. I stopped doing that when I branched out from just writing Gibbs/Ducky.
23 – When you post, where do you post to? Just your journal? Just an archive? Your own personal site?
24 – Betaing – How many betas do you like to use to make sure there aren't any major flaws in your fic? Do you have a beta horror story or dream story?
25 – Music – Do you listen to music while you write? Do you make playlists to get into a certain 'mood' to write your fic? Do you need noise in general? Or do you need it completely quiet?
26 – What is the oddest (or funniest) thing you've had to research for a fic?
27 – Where is your favourite place to write, and do you write by hand or on the computer?
28 – Have you ever collaborated with anyone else, whether writing together, or having an artist work on a piece about your fic?
29 – What is your current project or projects?
30 – Do you have a favourite fic you've written? What makes it your favourite? And don't forget to give us a link!
