I know of a few people that are probably going to have to rethink there link building strategy severely when the forum coders stick a simple rel into their profile pages! Seems as though profile pages are like marmite (love / hate) with people.. I'm not a great fan of profile links just for the mere fact I like links that will stick, and eventually (as is already beginning to happen) these will be nofollowed. I will use profile pages alongside other link building methods - but exclusively - nooooo! The amount of dollar that Xrumer makes on subscriptions must be mighty... it's only when you think of how useless that program will become when nofollow goes into play that you realise why the owner is probably squeezing every penny he can from people whilst it works! It's something to think about anyway.
