What Does #FF Mean?
Simple Answer: Follow Friday... It’s one of a handful of abbreviations used in Twitter that confuses new users, and then they avoid using it. 

I remember the very first time I saw #FF messages. My Twitter feed was littered with them but I couldn’t figure out what it all meant. I felt left out – what is #FF? what am I missing?! So, for those of you who are asking yourself those questions right now, here’s a short guide to Follow Friday…

#FF is short for #FollowFriday. It’s a Twitter trend created back in 2009 by Twitter users that has since become a customary Friday activity.

An #FF is a shout out, a show of appreciation, a nice thing to do. Each Friday you can recommend Twitter profiles that you appreciate and enjoy to all of your followers. The idea being that your #FF recommendation will encourage others to check out that profile, generating more followers for them. 

Sooo...... long story - short, this Tuesday's Twitter Tip is to show appreciation for a profile that you appreciate, and #FF them this Friday ;)
