We all have our reasons. Maybe your reasons change. For instance, maybe your tweets are different because you need a job, or maybe you only follow people you know personally, maybe you follow everyone, maybe you follow no one at all, maybe you just RT people, maybe you just post links, maybe you only broadcast yourself and don't reply to people or mybe you use Twitter because you love community and helping others. The last reason is why I do it.

Whatever reason it is, why do you do it?
