Johnny, as what you've said, to each his own, hehehehe

facebook, widely covers the global social networking, while QL isnt that prevalent. though anyone can join.

i prefer QL cause it helped me a lot with my mobilization here in qatar, and kudos to mods

but facebook is also favored in a different level.

anyhow, both are to be given credit, cause somehow they have part of each member's daily way of life.

just sharing my 2 cents :)
