Clearly defining segments of something as complex as the Social Web is a bit like trying to explain how men and women think; half of all people will most likely disagree with you. But will that stop us? Never.
This list is not definitive; It is, however, a great resource for showing our clients the complexity of the social web and where different opportunities exists.
So without further ado, here is are the 5 Spheres of Social Media, by the Stratius Group.
Networking
Broad social networking is what most people think of when they think “social media”. Myspace has captured the attention of the world with its widespread adoption by young online users and could be credited with much of the rampant growth the social web enjoys today.
The Social Networking Sphere includes all sites that are mainly geared around people meeting one another in a broad sense. These sites allow people to connect for various reasons, such as friendship, dating, resources, and careers. Most sites within this sphere will touch multiple other spheres as they try to provide as many valuable social media tools as possible to their users.
Publishing
Publishing, sharing and the promotion of various media is the focus within the Social Publishing Sphere. This includes the large subcategory of blogging, specific media sites for sharing video or photos, and reference sites featuring community generated knowledge.
Subcategories: Blogging, Micro Blogging, Music, Photography, Reference, Video
Linking
Sharing links to articles and other content, very often for promotion, is the priority of sites within the Social Linking Sphere. Many of these sites are referred to as “social book marking” sites, but this term looses accuracy since most of these sites are now geared towards sharing links or the promotion of content to other users as opposed to just saving them for later recall. Even a somewhat pure book marking site like Delicious.com is commonly used to promote links to others. Many of these sites utilize some type of accumulated voting value to promote the “most viewed” or “most liked” content for others to see.
Subcategories: Link Sharing, News Sharing
Interactive
Virtual, gaming, and crowdsourcing networks fill the Social Interactive Sphere. The focus of these networks is on dynamic interaction with others. The interactive portion can be a virtual 3D world that mimics our own, large gaming environments, or communities where users work together to solve problems and create goods and services.
Subcategories: Crowdsourcing, Social Gaming, Virtual Communities
Examples: Second Life, NameThis, Webkinz, Mosio, Threadless
Niche
Micro-focused networks that can really fall within or across many of the 5 spheres. Niche networks will begin to create much more valuable hyper-local online community content. But geography is just one section of niche. Site form around very unique interest from TV shows to sports and much more.
Examples: Kirtsy, Ning, My Church, Passport Stamp

The last Olympics definitely had some online flavor to it, but live events? That didn’t happen. The Beijing Olympics is the first truly online Olympics, in the sense that the Obama Campaign is the first presidential campaign to really use the internet. It has happened before, but no where near this scale or value of product.
Its pretty genius when you consider the immediate benefit he gains. One of the most valuable, after pieces of information in their campaign right now, will be given straight to their supporters. Its a great way to empower the supporters. Its right down the Obama “change” road. And of course he gets the cell phone number for thousands, if not hundreds of thousands of his most fervent supporters (and the entire press corps).
