LIKE US & We'll Like YOU back. To be fair, PLEASE reply with something like this:
"@ foreground: Liked you!"
So that ppl knows who liked who.. and like exchange that way is much easier.
ALSO, please use your PERSONAL FB ACC to Like, and NOT w/ your page acc!
ps: If you like someone's page using you Page's Acc, it will NOT boost the FB Like count.
We are sure many Facebook page runners are aware of this.
