Crickhollow remains on the lower end as far as population goes, and we are in the pre-expansion lull so activity is a bit low. I can't really say much about the endgame kins, other than my belief that their activity and membership have certainly dipped quite a bit in the absence of new content. But Crickhollow always struck me as a bit more casual than most servers, and you'll definitely find casual social kins of all sizes.
Second Breakfast still supports three weekly light RP events (Bread & Jam at the Pony on Fridays at 8pm EDT, early Elevenses on Sundays at 11am and evening Elevenses on Mondays at 11pm, both at the Bird & Baby) as well as the multi-kin band, the Breakfast Club (informal concerts most Saturdays at 1pm). More involved role-play isn't found as much these days, as our best and brightest gravitated towards Landroval.
You will likely find more activity on your other servers, but I always preferred Crickhollow above all. In the end, its often about the kinship you find and the friends you make. I wish you the best of luck in finding that great kin and the activities you'd like to pursue wherever you may end up.
