on the home page next to every item there is a [seen] and [stop follwing] selection. click stop following and then it goes off your list.

If you mean the long list of photo's and blogs on the left of your homepage Aitch I don't think you can.They are just replaced by new ones from the top.I know sometimes it's difficult to remember which ones you've seen and read :)

Yes, the list just keeps on growing but I wanted to delete them, if I could.
