An important technical rule governs the use of the “@” sign, which is the beginning of every account’s handle. If you start a tweet to someone with “@,” only that person and those who follow both of you will see the tweet. This is so you can have a semi-private conversation with that person without cluttering up others’ timelines. To make the tweet appear in the timelines of everyone who follows you, add a word or character before the “@” sign, even just a period.
