OK, I updated the download in the original post - I really didn't change much from the original. I did:
- remove the end post#, as it was preventing the subject from loading into digg and delicious correctly. It's not needed if you are only linking the starting post in a topic (as it is written)
- removed the extra span tags since they're redundant now
- update instructions for 7.3
I only included instructions for postside.tpl, they're pretty much identical for posttop.tpl if you want to put them there, I've never seen anyone use that tho.
I only included the 2 original sites too, if you want to customize this Ian's code is pretty easy to follow

I didn't include the nofollow tags - it can only help your site's SE rankings to allow the bots to see good links to and hopefully from the huge networking sites.
