June Something Day 7

Day 7: What's the longest time you've been in a fandom. Not necessarily your oldest fandom, but a fandom that you started and still continue to read/write/create content for in some way.

I've been a sporadic reader/lurker in the HP fandom for something like 22 years, so I guess that takes the cookie?

But I've been a writer in the SGA fandom for 2 years and seven days, plus another year or so when I jumped headfirst into the McShep fic and returned to reading fanfiction in a big way. :)
