I love it, mostly for its style and because it offers slightly more accurate data than Hivestats. For example, despite many "updates," Hivestats does not show the exact amount of Reputation an account has, whereas HiveLytics does. That alone makes it one of my favorites.
I'm not much of a data cruncher, I just focus on writing, but it's always good to see some information about your account and track your progress from time to time.
Excellent work.
