It can be hard to get new topics added. In particular, I know of the rejection of pages for an influential database technology (with US patents) and for a digital standards organisation, and yet there was a page for a US-based comedy series that was never shown in Europe. Not everything in the technical pages is correct, or even fully accepted. It can be seen that some of these pages have taken material from multiple sources that conflict with each other -- basically, some subjects have no precise or universally agreed description. On the other hand, some pages -- especially in physics or mathematics -- have almost been contrived to be unintelligible to the lay person. This is subtly important because it poses the question of whether the site is be educational or not.
