I came across the following tweet from someone who I am following:
Is twitter a social networking or a professional networking tool? I really dont want to know ur progress through the day unless ur a starlet
The choice is really yours, the users. What you absolutely can’t control is what others tweet. You decide who you want to follow. And even the people who tweet ‘professionally’ are also humans (unless you are following a bot or a company/publication, in which case this conversation doesn’t hold good). And humans are rarely uni-dimensional. Even professionals have families and friends and have other interests besides work. There will be tweets related to family and friends, movies they recommend, walks they walk, runs they run and hikes they take. Spouses will say funny things to be shared, children will fall ill and best wishes will follow. The beauty of the open architecture of twitter is that you can decide not to follow someone. However asking others to tweet to your tastes is expecting too much.
