I think a badger for 1000 or 2000 or whatever merits is unnecessary.
Merit already shows off in your profile. And the forum's discussions are too focused on merit already.

Badges could try to move the attention somewhere else...

Maybe something more bitcoin related. A community helper badger? I see some users like bob123 that are always helping users in the Technical Support board....

Or maybe a badger for a user that have completed bitcointalk courses?
