I haven't been here for the whole two years, but I have been here for the better part of a year and a half, so I figured I'd comment anyway 
I miss Denryu's surveys. I know he still does them occansionally, but it's not like before where there was almost a new one every week, and they almost never hit the 100-person limit.
I miss the "smallness" of the community back then. Don't get me wrong, it's great that there are a bunch more people interested in the game, but I used to know the screennames of pretty much every person who posted on a regular basis. You used to be able to read every new reply in every thread on the boards in an hour or two each day. Now it's almost impossible to keep up with just one subforum.
I also miss the sense of anticipation. Waiting for the first beta to come out was so excruciating 
I'll end my list of things I miss with saying that I miss the attempts to get inside jokes into the game. Bear calvary, obviously, but who remembers the Legendary Toothpicks of Boogiebac? (I'm also disappointed neither of those made it into the game, but that's another subject
)
I know I've been a lot less active than I used to be. Mostly that's because school is taking up much more time than I expected it to.
Oh, one more thing I almost forgot; I miss Wintersong's many chaning avatars. Back when the community was smaller and I knew everyone, I always found it entertaining to see what new avatar he would have each week/day/hour
