Of course I read them. Twitter is my main mode of communication. If you're asking about do I read spam and click on links that's something totally different. My main account that I actually have interaction with is for real people
Most of the time I like to give a quick I to those and read carefully if anyone seems important to me. Not like to read all the tweets as that is time consuming as well.
I like twitter way more than facebook. So im always on it reading, tweeting and retweeting. Its pretty fun.
I only read tweets for inspiration purposes. Some phrases or quotes to motivate and inspired me everyday.
