I like the simplification around the three central entities (things, people, organizations).  The site seems clean and professional.  I think it would be really helpful if you had a LinkedIn OAuth setup to allow users to import their prior &quot;organizations&quot; into your site.  That way they would just have give details to the &quot;things&quot; they&#x27;ve worked on (if they hadn&#x27;t yet been entered by a prior user).
