• The article is severely out of date. Not only the data is out of date (which should be relatively easy to fix), the relative importance of topics also reflects the industry ten years ago.

• The article contains uncited material
• See also is too long; are there duplicate sources or is the article missing significant topics?
• Sourcing doesn't comply to the weak GA criteria, with ' "Archived copy". Archived from the original on 2009-05-05. Retrieved 2011-03-29.' as an example (need more than bare url).
