We had 18 participants in our first mashup challenge. 10 of those posted on time (or the next day, including myself, doh), 5 of those have notified me they'll be late, and 3 dropped out completely. Of the dropouts, two cancelled each other out, having been assigned to each other because no one else shared that fandom, and one was to mashup my own fic. I have decided that rather than scramble for a pinch hitter, I'm not going to worry about getting my fic mashed up. For me, the fun of participating was in writing the fic. I've had an incredibly fun time, and while of course I am curious as to what someone would do with my fic, it's not that important.
So! Hopefully the last five fics should trickle in soon. As I said in the original post, this is not an exchange so much as an opportunity to write some really cool fic, so I'm not going to be riding people to get them to post by a certain date.
I'm quite happy with the way this went, and I hope you'll all consider participating again next year, and maybe we can even get a larger crowd.
If you had fun with this and don't want to wait a whole year to do something like it again, we also have
revisit_me, which is not a challenge, but just a place where you can browse through and see who has offered their fics up for mashing/remixing/whatevering, and write if you want. Or post with a list of your own fics.
