This is currently tagged as an extra-hierarchical region; text says (correctly, I think) that it overlaps the Peninsula (Bay Area) and South Bay (Bay Area). However, the latter article is just a stub and it says "The South Bay is sometimes described as Silicon Valley".
Should something be changed? Move some of the text from here to South Bay? Redirect South Bay to this? Perhaps vice versa? Adjust our region structure in some way? I do not know the area well enough to suggest answers, but the question seems worth asking. Pashley (talk) 22:48, 9 April 2014 (UTC)
