Micro-blogging is no longer a strange word. More precisely, it has become part of our life.
As for me, many factors contribute to the widespread of Micro-blogging. First, it is very convenient for people to express their instant feelings at any time. Second, it provides a chance for people to release their inner stress. By revealing their heartfelt emotions on the Micro-blogging, their friends may also know about their conditions and can offer in-time comfort.
However, Micro-blogging can also be potentially dangerous as it may give away people’s privacy and other significant information.
All in all, Micro-blogging provides us comfort and also inevitably some concerns. We should be careful while using it.
