Question What is a social network? 

Google Says:

Definitions of Social Network on the Web:

• The personal or professional set of relationships between individuals. Social networks represent both a collection of ties between people and the strength of those ties. Often used as a measure of social “connectedness”, recognising social networks assists in determining how information moves throughout groups, and how trust can be established and fostered.

• refers to structural characteristics such as proximity to others, frequency of social contact and the type of relationship (eg spouse, confidant, relative, friend, group).

• A social network is a map of the relationships between individuals, indicating the ways in which they are connected through various social familiarities ranging from casual acquaintance to close familial bonds. The term was first coined in 1954 by J. A. Barnes (in: Class and Committees in a Norwegian Island Parish, "Human Relations").

So what purpose does MySpace or the others with this type of social networking website format really provide that a personal blog would not?  After all those that run the Internet, you and me the small development community really isn't the whole of the Internet our Social Network?  For example take a look at what happens when Dare Obasanjo nags about functionality in Google Reader and Feed burner.  Blog Rants as Bug Reports.  So you can notice that with the advent of RSS and RSS aggregator like Google Reader our little Geekdom has cemented itself.  Developers of feedburner and Google subscribe to Dare and now their respected peer, thus they respond promptly his criticism.

I wouldn't call WordPress a Social Network but it does provide the bare free foundation.  You can start a conversation with the world add resource pages. Is there any thing missing from this equation except some one specifically telling you "you are not part of a social network called the Internet."?

Last night I asked do I really exist without any readers?  But I know I have at least three constant reader Google, MSN Search and Yahoo.  So perhaps the better question is do you really exist if you don't blog?  If you don't there is no real potential for your view points and insight to propagate through the Internet and to others in our little Geekdom.  I think blogging for Geeks is the equivalent to all of the more "Social networking" that is done in other businesses ie lunches and dinner parties.  But that's just my two since what do you think? and yes a blog with comments enabled begets conversation.
