The 70-year-old star said people should not look for anything else apart from fun on social media, reported People magazine.
"I look at it as entertainment. I don't take it seriously. It's easier to write a thought in 140 characters than it is to waffle on for acres and acres and acres of words. If it amuses a few people a couple times a day, great. They shouldn't look for anything more than that," Midler said.
The actress joined Twitter in 2010 and has shared her opinions on the platform, poking fun at everyone from Justin Bieber's dad to the first family of reality TV.
