Here is what I got back from wikipedia. I"m not surprised... we really don't have many sources outside our own community.
This submission's references do not adequately evidence the subject's notability—see the general guideline on notability and the golden rule. Please improve the submission's referencing, so that the information is verifiable, and there is clear evidence of why the subject is notable and worthy of inclusion in an encyclopedia.
What you can do: Add citations (see Wikipedia:Referencing for beginners) to secondary reliable sources that are entirely independent of the subject.
Remember that wikipedia is designed to be a reference, not necessarily explainging cutting-edge technology.
