Using the channel as a one-to-many method of broadcast advertising is viewed as bad. [craft]
The second danger is coming off as too self-promotional and therefore narcissistic or uninterested in others. There is a sense, especially with regard to technologies like Twitter, that the service's “proper” use is to share personal information with others. Using the channel as a one-to-many method of broadcast advertising is viewed as bad form and an indicator of low status.
