Indeed followers are a great number but doesn't mean antything in terms of bonding and 'fiendship'. I recently celebrated my 400th follower ;) But I think only 1 % really read my posts (ok perhaps some more). I think it is more important to interact with the persons or subject you're really interested in, that way it is a longer run bonding.. (i.m.h.o.)...
But congrats of course....4000 pfiew.....
