My experience

Unfortunately not that much interaction

Primary used for self-promotion

Partial really high quality tweets

„Must have more followers“

Only a hype?

Pros Still no profit A lot of nonsense-tweets Only self-promotion

Cons No real competitors (Plurk, Jaiku, Identi.ca) Filtering information by (de)selecting followings Twitter is good for…

Getting insider information High quality information (with the right followings) Getting information fast Getting everything!?
