I set out to create the exhaustive list of social networks but only got exhausted. Wikipedia lists nearly 200 active sites and I found another 100 or so without difficulty. As I thought about it, it’s such an evolving landscape that this snapshot would become outdated the minute I hit “Publish”.
Since a picture is worth 1000 words, I thought one would be a better of way of depicting this information. What have others done previously? As it turns out, an image search for “Social Media” or “Social Network” turns up a bunch. Here are a few I like.
In October 2007, Robert Scoble did a video defining the Social Media Starfish. In his definition, “Conversions” are in the center and they are surrounded by the following 12 arms: Blogs, Photos, Videos, Personal social networks, Events, Email, White label social networks, Wikis, Audio, Microblogs, SMS and Collaborative tools.
Darren Barefoot created the following illustration of it for Scoble.

Seven months later in June 2008, Fred Cavazza created the following diagram to describe the social media landscape. In his view, social media has the following 10 elements: Publish, Share, Discuss, Social Networks, Microblog, Lifestream, Livecast, Virtual Worlds, Social Games, MMO.

In August 2008, Brian Solis and Jesse Thomas worked together to create the Conversation Prism to map the social media landscape. Over time, social media expands, evolves and morphs. Solis and Thomas recently release the following graphic as their third version of the Conversation Prism released. Their tentacles consist of the following 28 groupings:
Comments and Reputation
Wisdom of the Crowds

Collaboration

Blog Platforms

What do you think of these models? I’m working on my on view of the social media world and would love to hear your two cents.
