A Twitter user named "Distance Education" with the user name ‘onlinecourse’ has followed me 25 times. This suggests that they have also unfollowed me at least 24 times. This kind of behaviour I’ve heard called ‘follower-churn.’
I may have accidentally unfollowed someone, and then followed them back. I certainly haven’t been using this to gain followers. I follow people because they are interesting to me, and I manually follow each person I find, after reading through some of their tweets. It’s a bit onerous, but it does tend to ensure that I get a better selection of information from the people I’m following.
Distance Education is currently at 6565 followers. I have roughly the same number. Who do you think is interested in actual engagement, and who is just looking to pad their numbers? Hint: It’s called social media for a reason.
