As you will see Plurk can also be used to display WordPress posts using the Wp-Plurk addin – from here http://www.ferdianto.com/wp-plurk or via the wordpress plugins site
So as you write – you can have your display updated. Short and sweet
Actually there may be a compatibility issue with 3.1 and Wp-plurks so not so much plurking today
Update – yep it seems that the update to 3.1 may have broken several of the plurk addins that worked on 3.0.5 – so check back soon and see if this is running
