<script type="text/javascript" src="http://identi.ca/js/identica-badge.js">
            {
               "user":"martinolivera",
               "server":"identi.ca",
               "headerText":" y sus amigos"
            }
</script>

Así le puse al mío:

<script type="text/javascript" src="http://identi.ca/js/identica-badge.js">
            {
               "user":"rbonifaz",
               "server":"identi.ca",
               "width":"200px"
            }
</script>
