How does "Web2.0" helps in social networking?

According to Wikipedia’s definition, Web 2.0, a phrase coined by O’Reilly Media in 2004, refers to a perceived second generation of web-based services—such as social networking sites, wikis, communication tools, and folksonomies—that emphasize online collaboration and sharing among users.”

The key aspects of Web 2.0 sites are:
a). Rich and interactive user interfaces.
b). Involving others for active participation through social networking.
c). Improved and continuous upgradation of software of data at a very quick pace.
d). Modifications and remixes by other users to the content to add more value and consequently encouraging data consumption.
e). It’s a global platform linked with Social Media to generate traffic via Social Networking and Social Media’s.

Web2.0 is all about Social networking of Social Media, or to be more precise, it’s all about connecting to each other through Social Media sites. Social Media includes Social Photo Sharing (flickr, picasa, photobucket, etc.), Social Networks (MySpace, Facebook, etc), Social Bookmarking (del.icio.us, diigo, furl) . This is a very important section where we build up networks all round the Global. Sites like MySpace, Facebook, Live Journal, TagWorld, Disney XD, Toyota Prius, MSN Groups, Yahoo 360. The term itself describes its features as this section of Social Media explains the sole method of creating and building social relationship out of nodes and ties. Well its pretty obvious how these social networking sites helps in tie-in up of different social network, all round. (MySpace, Facebook, etc),

If you are an online marketer, then the Web2.0 formulae will be much clearer to you than a normal person. When your website visitors will participate and submit content (text, images, pictures, videos), links, participate to discuss and comment, build network around as a end user (both you and your site visitors), then it will enormously help you to generate more online traffic and this whole process will be services and applications of Web2.0. For example, Web2.0 helps to encourage and motivate people, via Social Networking, to make quality contributions to the content on offer. This would not only make proper justification to the same but also add value to it. So it is very important to encourage and motivate others to participate and contribute so that it continually improves the whole service for all of us.

All in all, web2.0 can be advantageous in social networking by its features like interactive users interface, applications, motivation of participations, data consumption encourage, and somethings like that.
