A few bookmarklets I converted to Pentadactyl commands...

pentadactylrc

" Bookmark page with Pinboard.in
com -nargs=0 pinboard execute "open " + function(doc) { if(doc.getSelection){s=doc.getSelection();}else{s='';}; return 'https://pinboard.in/add?next=same&url='+encodeURIComponent(doc.location.href)+'&description='+encodeURIComponent(s)+'&title='+encodeURIComponent(doc.title) }(content.document)

" Read page later with Instapaper.com
com! -nargs=0 readlater -javascript -desc 'Send current page to Instapaper' try { let doc = content.document; dactyl.assert(doc.body); doc.title = '(Saving...) ' + doc.title; doc.body.appendChild( DOM.fromJSON(["script", {type: "application/javascript", src: "http://www.instapaper.com/j/CJFRXrpfV0rU"}], doc)); } catch(e) { dactyl.echoerr('Please wait until the page has loaded.' + e); }

" Have more? :)
