Everything you do, and everything you say on Twitter reflects how the rest of us see YOU as a person.
It isn’t about all those links you share, it isn’t about how often you retweet your friends, and it certainly isn’t about how many followers you have.
It’s about how you behave.
Each time you update on Twitter, you’re telling us something about you. If you’re consistent in the things you say and write about, the rest of us can quickly build up a fairly accurate profile of who you are, and what you represent.
