MicrobloggingMicroblogging is a form of blogging using short posts without titles (known as microposts or status updates).

For example, a search within Instagram for the hashtag #bluesky returns all posts that have been tagged with that term. After the initial hash symbol, a hashtag may include letters, numerals, or underscores.
