Twitter's primary uses are for News, Entertainment, and Networking. If you have a business, networking is mandatory for your success.
"Twitter is the only platform that doesn’t have much friction when it comes to making introductions, so take advantage of that." @HilzFuld
It's much easier to introduce yourself to strangers on Twitter. It's part of the culture. After exchanging emails, you can easily move these relationships offline.
What Are The Rules of Twitter?
Sure, there are no written “rules” for Twitter. But there is a common etiquette. The main rule is, "Remember who you are talking to." Remember that you are building relationships. Think about how to bring value to your followers. Oh, and go easy on the hashtags.
