I must confess I find LFL a bit US centric for an organisation with world wide ambitions like BC, GC and LT.
What is GC?
I think LFL would also like to be more accepted and spread worldwide, but it is a relatively new organization and (to me, anyway) not as sophisticated as BC and LT, which have been around for a while. LT just celebrated its 10th anniversary. I've been a member of BC for 12 years!
I also think that LFL turns off many individuals (probably more in countries other than the USA) by requesting the fee to become a charter member. Both LT and BC have the option of free membership.
In addition and to my knowledge, LFL has not been including other languages in their marketing yet. I might be wrong about this, though.
