I'm looking for a map of large or important high-tech Silicon Valley companies: Apple, Google, Yahoo!, Facebook, Twitter, Tesla Motors, AMD, Intel, HP, 23andme etc.
There's a poster like that here
, but its very old (no Facebook on it).
I figure some Google use must've created a "My Map" of these companies, but I'll be damned if I can figure out how to search public Google My Maps (as a test, here's a public My Map of mine with apartment complex in the SF Bay Area
; try searching for it).
Other ideas? I'd be happy mashing up some sort of KML with Google Maps, if it comes to that.
