Social Network Taxonomy
I continue to explore Social Media using the structure provided by Charles Heflin (see my post "Top Industries with Social Media Potential" on July 29th, 2008). Charles separates social networks into four categories:
- A NETWORKS - Have the functionality for you to create a group, blog or channel within the network and any combination of elements from B, C, or D NETWORKS. A NETWORKS must also have the ability to mass communicate with members of your group, channel or blog.
- B NETWORKS - These networks may have all the elements of an A NETWORK but they lack the ability to mass communicate to your friends, group/channel members at the same time using a messaging interface. The most common use for B NETWORKS is social bookmarking and content syndication.
- C NETWORKS - Are RSS feed distribution networks.
- D NETWORKS - Are tools to enhance your marketing efforts. They are not a place to market in themselves but could enhance your marketing in other channels.
In this post, I have listed over 100 websites that are positioned as social media, and attempted to classify them based on the above. I have found that a descriptive name helps me keep the four categories straight. So, I replaced "A" with "Mass Communication", "B" with "Community", "C" with "Promotion" and "D" with "Utility". This study is not comprehensive, and it is not perfect. The list has the following attributes to aid in the classification process:
Sub-Category
Name
URL
People Count (Compete.com)
PageRank (Google)
Description
Purpose
Messaging
I've already described the Network attribute above. The Sub-Category is mostly relevant for the "A Network" or "Mass Communication". They are "Blog", "Personal Content Aggregator", "GeoNetwork", "Group", "Microblog" and "Topical". I think these are self-explanatory, but if not - just comment and I'll provide additional clarifying information. The other two attributes that need some explanation are "Purpose" and "Messaging". The "Purpose" attribute is my attempt to assess the purpose of the website. In most cases, the purpose seems to be either "People Discovery" or "Content Discovery". The "Messaging" attribute is an attempt to classify the type of messaging facilitated by the website, and is relevant only for the "Mass Communication" networks. As an example, with Twitter you can message the entire community, with Plaxo you are limited to your network.
So, here is the published Google spreadsheet with my list. It has three views: alphabetical, people count order and PageRank order. I will continue to update this list on my own, but would really appreciate your thoughts - what have I mis-classified, what sites should added, etc.
