How do servers gain 'Legendary' status?

[grebnev]

So I'm returning to EQEmu after playing emulator servers mostly in the 2000's. How do servers become Legendary status--is it a player count thing, amount of traffic coming through, maybe community voting?

I particularly have Shards of Dalaya in mind; it's the one server besides P99 that really comes to mind when I think 'legendary', being around since '02? if you count the Winter's Roar days. And I don't think I've ever seen another pserver for any MMO that essentially builds out a whole new full-scale game like SoD does. Wish it were up there to help it get the attention it deserves!
