  == External links ==  I noticed this article at the top of a list of articles needing external link cleanup at Wikipedia:WikiProject External links. At 90 links, it was by far the most heavily-linked article on the list, and although these links were pared down at one point, they have made a comeback. The last edit on January 8, 2007 added 70 external links, most of them without descriptive text. I suggest that someone familiar with the subject of the article go through and select only the most essential links to keep, so that readers will be directed to the ones that are most likely to be interesting and rewarding. Wikipedia is not a link repository, and excessive linking distracts from the article and makes external links less useful/meaningful. -   -  - wpn)
