According to google analytics, Nevergrind's average visit duration is now 13:36 over the last 30 days. This seems pretty good to me! I know several months ago it was closer to 1-2 minutes, so I figure the new features like leaderboards and quests have people more interested in developing their characters. There are still very few visits per day (about 20), but it appears the few that do visit are fairly dedicated.
Anyway, just wanted to highlight that metric. It's the one stat that keeps me going
