is the list of banned domains, it is not on there.

I checked another tutsplus submission:

http://news.ycombinator.com/item?id=632213

and it too is dead.

So chances are it is on the banned domains list.

I think it is because tutsplus steals content:

http://blog.tuvinh.com/top-20-mysql-best-practices/

vs

http://net.tutsplus.com/tutorials/other/top-20-mysql-best-pr...

I think this is the non-syndicated link to the same article:

http://blog.caointeractive.com/how-to-make-all-browsers-rend...

It does contain a link to tutsplus at the bottom.
