91% out of "Everyone" (27), with the few that I missed mostly people who haven't posted in a long time, or memes with no other content. Scarily enough, I was able to get eladria and aerin both on meme-only entries. The fact that they were both Firefly memes didn't hurt. :P
The easiest of all was theferrett , since his post about the meme was the one that came up for his journal.
