Social networks are one way of getting in touch (or stalking) people or celebrities who we would not have any other contact with.
A colleague of mine recently joined Twitter and quite quickly became addicted to the social network.
Shortly after joining, she confessed she was spending several hours a night glued to her Twitter feed.
This particular colleague already had a Facebook page but had previously shown no interest in Twitter so, after quizzing her as to why she joined, she told us it was so she could follow her favourite singer.
The singer has a managed Facebook fan page and my colleague believed she could make contact with the singer via his Twitter account.
