"Hi, I know this is exceedingly random, but could you please comment on cuddled's journal? She seems to be a really nice person, and she's looking for 1000 comments by Christmas. If you don't want to, that's ok, but I, and she, would really apprieciate your time.
You can comment here, if you're feeling nice.
Happy holidays, and spread the word!"
Just do it! :-)
