Lordaeron

I wanted to start a new char in lordaeron and the question is do people still play in that realm? mean is it fun and easy to find people ?

Yup, it's pretty active. Not as active as Icecrown (because it's a 1x server and too many people have the "now" mentality).

Edit: Here is a link to how active realms are
