Twitter is an online news and social networking site where people communicate in short messages called tweets. Another description of Twitter and tweeting might be microblogging. Some people use Twitter to discover interesting people and companies online, opting to follow their tweets.
A Twitter account is your passport to what's happening in the world and what people are talking about right now. By signing up for an account, you're among the first to know about breaking news and what's popularââfrom the funny to the uplifting to the surprising.
The default settings for Twitter are public. Unlike Facebook or LinkedIn, where members need to approve social connections, anyone can follow anyone on publicTwitter. To weave tweets into a conversation thread or connect them to a general topic, members can add hashtags to a keyword in their post. The hashtag, which acts like a meta tag, is expressed as #keyword.
Twitter vs. Instagram. While Twitter is used for sharing ideas and catching up with news and trends around the world, Instagram is meant for sharing your best photos and videos with your followers, as well as interacting and engaging with influencers.
