Clearly this meme is going the rounds! Copped off brightknightie, who adapted it from used_songs, who got it from shipperslist:

Of 267 fanfiction works...

Under which 3 ratings have you written most?
218 General audiences
44 Teen and up audiences
06 Not rated

In which 3 fandoms have you written most?
95 Forever Knight (TV 1992)
88 Mary Renault's The Charioteer plus RENAULT - WORKS
13 M*A*S*H (TV)

I've got 44 tagged as "The Charioteer" and another 44 tagged as RENAULT - WORKS. The latter are ITOWverse stories which were written for maryrenaultfics, and really count as having been written in relation to my interest in The Charioteer. So maybe best combined.

Which 3 characters have you tagged the most often?
52 Nick Knight
27 Natalie Lambert
24 (tie) Lucien LaCroix
24 (tie) Laurie Odell

What are your top 3 additional/free-form tags?
43 Metafiction
40 Backstory
24 Historical

The Metafiction ones are almost all ITOWverse stories.

Did any of these surprise you? If so, which?

Actually, the only thing that surprised me was the fact that I've actually got 20 stories tagged as "Christmas". And two rated Mature.
