You wonder if Six Billion Secrets is going to change its name to Seven Billion Secrets when we hit that population this year, amirite?

I never realized why it was called "Six Billion" Secrets until now.

No. Instead, the site creators will change its name to fit what it has become:
Seven Billion Shout-outs, PSAs, Y U NO SEE THROUGH MASKs, OMG I LOVE HIMs, I'm going to post this even though it's common sense's, I wish I was beautiful's, ohh it's all my fault's, ...

...the list goes on and on. There are rarely any actually good-quality secrets posted.

we already hit 7 billion...

there are actually over 9 billion peeps on earth <3
