The social networks you should be a part of
Facebook is the king of social networks, rivaling only with Twitter due to Twitter’s ability to easily mass-promote and connect with others.
FriendFeed
FriendFeed is a simplistic social network that lets you bring feeds from a variety of sources, including Facebook, Flickr, Twitter, and your RSS feed, into one central location. Additionally, FriendFeed can post updates to other social networks, including Facebook and Twitter.
LinkedIn is a social network site designed more as a resume-style site, but there’s definitely the basic social networking aspect involved. You can use LinkedIn both as a way to network with professionals, and to participate in typical social networking.
MySpace
An oldie but a goody, MySpace is one of the original social networks, and while it’s now very music and independent artist oriented, it’s still worth participating in.
Ping.fm
Ping.fm is not so much a social network as it is a type of forwarding service that will take updates you send to it and forward them to a variety of social networks and even IM clients and sites, such as Yahoo. I personally use Ping.fm, and I love it.
Twitter is worth using, period. Need I say more?
