One area that has become very popular within the social networks is the hashtag. This is the ability of people to mark with a prefix specific areas of interest to mark their keywords that can be searched. This makes it easy for other users to find the topic of interest. But, an additional advantage is that the hashtag is tracked to determine how it has been trending. The more it trends up, the more people follow it till the next popular hashtag comes along. However, some hashtags like #dogs are probably always popular.
Typically, for a company it is useful to create a few hashtags specific to its company and its product. That way it is easy for the company to track its product but also to determine what has been the following. However, too many hashtags is messages may be very confusing and not serve their purpose.
