This is somewhat a self-centered question, but I love this site and yet at the same time feel my interest flagging recently, so I'm looking for some guidance from others who have and remain loyal and active here.
The gamification aspects of the SE model were enough to get me engaged initially, and kept my attention for a while.
I can't remember quite when it happened, but I think around the 10K mark, when the last "useful" (by my lights) privileges are earned, I stopped caring about rep¹.
In part, this makes my use of the site more enjoyable; I can be more casual, care less about the inevitable spats, take my time to offer comprehensive answers rather than fast answers, and so on.
But, as a side effect, it also makes me less motivated to provide answers at all. This effect, combined with the fact that I'm usually visiting the site from a phone, a device designed primarily for consumption rather than production (i.e. with inconvenient and handicapped input capabilities), is the reason you guys have to periodically chide me to convert my comment-answers into answer-answers².
Today, I noticed that SE has added a new tier of privileges, "Access To Site Analytics", which at a high level promise "three graphs show a timeline of posts, votes, and traffic" as well as access to a full Google Analytics dashboard. That sounds neat!
So, finally, on to my question: for those who have this new privilege, and use it: is it fun? Has it given you any interesting insights into how people use the site today, or ideas for how we could shape people's use tomorrow? Is it a draw for you to visit the site more frequently? Is it worth (probably) a couple months of investing time and effort to earn another 10K points?
Outside of that, for those of you who have 10K, 20K, 30K+ and are still growing: what brings you back? What motivates you to answer or ask questions? How do you keep the site fun for yourself after a year, or two, or three?
¹ Or, more precisely, I stopped caring about rep, qua rep, at about 2-3K, but I continued trying to gain it until I earned the last few privileges I thought would make my time here more satisfying.
² Though I will take this opportunity to note that it's always fair game for anyone sees one of my comments and likes it, to go right ahead and convert it to an answer himself.
Consider this permanent and carte-blanche permission, so you don't even have to ask me. Heck, you don't never need to attribute or cite me! Feel free to either quote directly or paraphase, and bend, fold, spindle, and mutilate to taste. The only thing you can't do is put words in my mouth.
