A disadvantage of social networking sites is that they are making traditional relationships obsolete. Some people use social networking and never bother to call their friends or visit with them.
Social network sites such as facebook have this thing called cash (like facebook cash) and uses will have to spend money to get some. Another way they make money is that the aplications on there have to pay something kind of like rent (like a shop in a shopping mall) so they also get money of the aplications.
Social networking sites usually carry adverts - the advertisers pay the web-site owners to allow them to advertise on their page, because they know they'll reach potentially a massive customer base.
Some companies will check social networking sites when hiring. The easiest thing to do is to make sure your profile's are kept private so that only people you know/trust can view your details.

Social networking sites are ideal to promote or advertise a business. Most social networking sites will sell ad space. In many cases you can create a user account to promote your product or business. You should probably check with the site administration first to make sure you are not violating any TOS. www.ManTurf.com sells ad space and even for web page sections for business owners. ManTurf deals directly with the gay and bisexual community.
