Twitip has an interesting post, The Quest for 5000 – How many Followers are Enough, written by Mark Hayward (mark_hayward). While preparing for the post Mark asked the question at Twitter, some of the answers are included in his post. My answer was:
Does not matter to me but I am picky with who I follow since I am interested in conversations.
Mark is shooting for 5000 followers and gives his reasons in the post above. That number makes perfect sense based on his aim with using Twitter, marketing his business and projects.
My aim is different, I use Twitter for social purposes and see it as my water cooler and enjoy the conversations. My coaching business is (so far) local and I am not likely to find any customers through Twitter. I follow people with interesting and engaging tweets.
When I get a follower I check their profile and latest tweets, if it looks interesting I follow back. Those I at first decided not to follow back that start a conversation I start to follow, my decisions can change.
Being active on Twitter is in line with all of my three key words: Trust, Connect and Grow.
