I've only been here a little over a year, but I think the Kon threads - 2013 and 2014 are fun, with pictures. The Selfies thread. MiseryChastain's thread "Who Are You Really? is a good recent one.
The thing is, this new board format just began last year (Halloween or Nov 1, I think), so there's not really old stuff on here. There's lots of folks who've been on forever, but the content of the board is new. The Cantina is where I got to know many friends. And sometimes just being bold enough to private message someone or give them a profile post is fun way to get to know someone, and it's a little more personal. I'd look through Chattery Teeth and find the really long threads - that means there was a interesting/heated/funny/controversial topic going on with lots of personalities shining through.
I enjoy your posts and am happy you're here. I'm probably not the right person to answer this, but as a newish person myself, that's how I have gleaned through things.
