Twitter is a well-known social network and everybody wants to have as much followers as it can be. In this respect, you can just stay and see who is following you, or you can take measures in order to increase this number. You can go on following any person that seems to be interesting and they will follow you back. You need to manage your followers, so the ones that have not followed you back, should be unfollowed. You will get followers with a lot of patience.
