I have received several messages from visitors offering a swap follow. What I mean is they will offer to follow me "if" I follow them. I personaly think that is high schoolish. Follow me because you like my content and you like what I offer, don't follow me in hopes that I will follow you to make you popular. That lets me know that you are not into blogging for the love of it; you simply want to be popular.
I would love to have more followers, but I want them to follow me because they chose to not because I solicited them.
