I thought such a small character limit didn't really allow for much in-depth conversation and that most posts would just be about what you had for breakfast that morning. And while I wasn't completely wrong, it's still a great way to communicate news instantly and communicate with others with ease. It's the only social networking site I can stomach now-a-days.
