			<content:encoded><![CDATA[<p>In her round up of Social Media moments &amp; milestones to remember from 2007 Susan Mernit finds one really tough problem<br />&nbsp;<a href="http://susanmernit.blogspot.com/">Susan Mernit&#8217;s Blog</a> <br /> <br />
<blockquote>Once we scale beyond the 150 or so people a high schooler might know, technology and standards become essential parts of the tool set and that’s the problem set no one has yet elegantly solved.</p></blockquote>
<p>Since I couldn&#8217;t post the comment on her blog (I&#8217;m not sure if it took), I&#8217;m responding here:</p>
<p>	Susan,<br />
Great post. I&#8217;m sure it&#8217;s not random that you used &#8220;150&#8243; as the number<br />
of people a high schooler might know. It&#8217;s considered the Dunbar<br />
number, <a href="http://en.wikipedia.org/wiki/Dunbar" s_number="" rel="nofollow" target="_blank">http://en.wikipedia.org/wiki/Dun&#8230;Dunbar&#8217;<br />
s_number</a> a theoretical maximum number of individuals with whom a set of people can maintain a social relationship.</p>
<p>I&#8217;ve got 2x Dunbar number in Facebook and it is slowly driving me<br />
insane trying to remember who some of the less-strong contacts are.<br />
I&#8217;ve kept LinkedIn down but it&#8217;s creeping past 200.</p>
<p>This is a difficult problem in that the systems we have aren&#8217;t<br />
providing good tools to create sub-groups. Facebook just came out with<br />
something called &#8220;friend lists&#8221; <a href="http://blog.facebook.com/blog.php?post=7831767130" rel="nofollow" target="_blank">http://blog.facebook.com/<br />
blog.ph&#8230;post=7831767130</a><br />
  but it&#8217;s really just list management. </p>
<p>I hope 2008 sees a way for us to more clearly designate not just lists<br />
of friends, but contexts in which we want to communicate. I know some<br />
party folks I want to see pictures from, but I don&#8217;t care what bands<br />
they listen to, etc. <br />
Not a trivial problem. </p>
