Many news sites post the next day's contributor columns several hours before providing a link on the website. Since these typically use a standard, date-based URL, I've created JavaScript bookmarks that automatically update to check if tomorrow's column has been posted.
For example, the following bookmark will check to see if David Pogue's latest State of the Art column has been posted. (Since his feature runs every Thursday, the bookmark will pull up his next column when it's posted on Wednesday afternoon/evening). The standard URL format for his column is:
http://www.nytimes.com/YEAR/MONTH/DAY/technology/personaltech/DAYpogue.html
So my JavaScript bookmark looks like this:
javascript:d=new Date();window.open("http://www.nytimes.com/"+d.getFullYear()+"/0"+(d.getMonth()+1)+"/"+(d.getDate()+1)+"/technology/personaltech/"+(d.getDate()+1)+"pogue.html", "_self");Mac OS X Hints
