Just like he wants you to believe that nofollow links are worthless ;-)
If you could enlighten us as to why they are NOT worthless, that would be greatly appreciated.
There are some great articles and discussions on this around the place. I'm not going to re-hash it again here as my concern is that it turns in to a "meta keyword tag" (remember that?!) scenario i.e. once everyone starts doing it, idiots will do it wrong and the whole thing kind of falls apart for those who are doing it properly.
I would of course like to thank wheel too for sharing a nicely deep tutorial on good link building. The fact what he said is nothing new compared to 5-10 years ago simply encourages me that the majority of webmasters must still be doing it wrong! ;)
e.g. all those people that buy link exchange software to scrape email addresses and spam them.
Thank goodness, or else I probably would have gone out of business years ago.
