Generally servers with more people are less fun. I enjoy a server more if it's 2-10 people and we all know each other to some extent. Our houses are more spread out making it possible for large farms, mines, mobs towers, anything a player would need sufficient space to build. On servers like your's, I saw nothing but houses for hundreds of blocks in every direction. And they were cramped.
I also noticed you had lockette. This is a fine mod to use on more populous servers, but it ... completely ruins the survival aspect of the game for me. I enjoy to have that constant fear of a player possibly wandering around and finding my loot, only to run off with it. This also contributes to the idea that more spread out homes are better.
Though, these are just my opinions. Other players enjoy servers that are set up like a metropolis and have iConomy installed, stuff like that. You still have a fine server Trifax. ;)
