What is a microblog?
A microblog is a type of blog that differs from a trad-itional blog in that it allows the posting of very short con-tent. A microblog allows users to share small elements of con-tent such as video li-nks, individual images, or short sentences/messages quickly. In simple words, rather than writing lengthy text, a microblog restricts to writing short messages that can appear in several con-tent formats, including video, audio, text, images, etc.
With microblogs, short messages can be shared with an online audience to improve engag-ement. So-cial me-dia chan-nels like Fa-cebo-ok, Ins-ta-gram, and Twi-tt-er provide popular plat-forms for microblogging.
