Sure, you can interpret it that way! But the original complaint seemed to imply that a majority (ie more that 50%) of content/discussion here is about/by Silicon Valley topics/ people.
If 90% of usage is outside SV, that leaves plenty of room for content/discussion that is not focused on SV, which is exactly what we see.
But let’s not get into a debate about the meaning of vague terms like “heavily” :)
