8 Types of People Who Belong on Twitter
The Promotion Channel
Both spammers and e-commerce sites fit into this category, but the e-commerce sites use Twitter in interesting ways to do promotion and inform customers about products they are interested in. Take a look at Amazon on Twitter. Their feed is a little bit all over the place in terms of content, and they don't have an individual person that followers can connect with (which limits conversation and can limit follower numbers) but they've still managed to collect almost 4,000 followers as of the publishing of this article. Contests, Twitter-only discount codes, and free giveaways are all part of the promotion channel arsenal.
