Removal of commercial link  I certainly have no problem with the trend toward not allowing commercial sites to use wiki as a spam platform  However many commercial sources are used when they are obviously also legitimate sources of expert information Example The Chicago Tribune is a commercial web site yet a legitimate source of wiki information  The links to free information and history pages on the commercial web site Just Art Pottery Just Art Pottery is another such example The owner of the site is widely known as an enthusiastic collector of American Art Pottery is very generous with information is sought after as a public speaker on pottery and is willing to help anyone who has questions about pottery Yes he sells pottery That is not a crime He is also an invaluable reliable expert resource on this topic  I feel strongly that the links to the Just Art Pottery information pages should be restored they were deleted There is a fine line between blocking spam links and having a kneejerk antibusiness bias
