Social bookmarking or Social networks?

I guess both, since socialbookmarking is really a great help in driving traffic to your site, same with social network, since twitter and facebook are an example of social network, since twitter really helps in gaining traffic everyday to your site, based on my experienced, I don't know about others.

Hello friends,
Social networking is a actually defined by linking people to each other in some way. Facebook is a popular example of a social network. It permit you to communicate with people online in a social way that a website would not. Social bookmarking is the ability to save and categorize a personal collection of bookmarks and share them with others.

Both have different way sending traffic and depend upon the experience you have with these.

Do both as they bring traffic rather weel

Hello

If you spend any amount of time on the Internet then you are aware of the vast number of social networks there are to choose from.

When you are beginning your social networking campaign you should decide which of these networks are the most relevant for your purposes. For instance, if you want to join a network for professional business contacts then you should join Facebook rather than Bebo or MySpace (unless you’re a musician). On the other hand, if you want to promote a hip new clothing line to teens, then LinkedIn is the last place you’ll want to be.

In order to make an informed decision about which networks to join you will have to do a little research. Figure out what your goals are, who your target audience is and then read some articles and look around in different networks to see where you could best achieve those goals. Don’t sell yourself short on research time—choosing the right networks is one of the most important keys to social networking success.

Thanks

Obviously it's from social networking sites, and from social bookmarking sites you can get traffic as well as backlinks. So both are equally useful for a site's promotion.

Joe is right, social networking can drive traffic, particularly twitter. Whereas bookmarks are useful for backlinks, stumbleupon is good as it is allows do follow. Although Bookmarks are great in the rare instance where you do get a really popular item.

both are capable to deliver a good/huge amount of traffic and its effectiveness will depend on how you will use them.

to drive traffic to your site you will explode every possible method and as much as you can. the more exposure the more visitor you get, its just a numbers game.
