Here's a handy bookmarklet for posting to Drupal from a bookmarklet:
javascript:var nodeaddpath="http://www.example.com/node/add/article",d=document,w=window,e=w.getSelection,k=d.getSelection,x=d.selection,s=e?e():k?k():x?x.createRange().text:0,l=d.location,e=encodeURIComponent,title=""+d.title+"",body="> "+s+"\n\nFrom ["+d.title+"]("+d.location+")",url=nodeaddpath+"?edit[title]="+e(title)+"&edit[body][und][0][value]="+e(body);nourl=function(){w.location=nodeaddpath};a=function(){w.open(url,"quickpost","toolbar=0,resizable=1,scrollbars=1,status=1,width=424,height=570")||(l.href=url)};/Firefox/.test(navigator.userAgent)?"about:blank"==l?setTimeout(nourl,0):setTimeout(a,0):"about:blank"==l?nourl():a();;void(0);
