it's very useful. But it's very difficult to do, even you cannot easy to find a paid service to do it
Even though the links are no follow, it is a quality link to have for every business. Great post Noah,, I agree that not enough take advantage of such a trusted resource site.
Thanks, I knew that though. It's not easy to sneak out in wikipedia ... Usually it's good with pretty unknown language pages, like French. For major languages there are evil moderators every where. And they will ban you without thinking. @ruzler, that doesn't matter Like yahoo answers(no follow too), these links are very valuable by google.
Pretty interesting tips and i do agree having an article at wikipedia gives you the brand authority for a certain keyword.
