what i've learned

diigo bookmarklet

because the diigolet and the diigo extension do too much

javascript:(function(){ 
  window.open('http://www.diigo.com/post?url='+
    encodeURIComponent(document.location), 
    'DiigoBookmark','width=490,height=630,
    toolbar=0,resizable=0,
    location=0,scrollbars=0,menubar=0')
})();

i can’t create a link b/c tumblr escapes the javascript and breaks the link but to get it to work just create a link with the above as the href (sans whitespace) and then drag the link to your bookmark bar
