They have yet to fix the most glaring problem: Tee fact that any setting other than "total transparency" cannot be selected whilst configuring your privacy settings.
Wrong, you
can lock everything up, they just make it so every time there's a new privacy update the default setting re-opens everything back up unless you hunt around a bit. I still missed things even knowing this at the last privacy revision though, took me several months to finally work out how to lock up the final bits of my account on there.
As such I'm nigh-on impossible to find on it, but it takes some doing to get to that stage.
Anyway, Faceaids search is total crap. It doesn't work properly and never finds the results you want. Google have nothing to fear.
Also, the Faceaids admin aren't very tech-savvy. Couple of years ago they were complaining about how CPU manufacturers weren't making CPUs that ran PHP code fast. You know why they weren't? They were busy making CPUs that run
native code fast. Odd that eh? PHP is interpreted and it's slow as a result. However that allows it to be powerful whilst not impacting dev time (although there's more powerful and faster languages around that let you code quicker as well, but they require you to be able to
read nonsense).
As a result Faceaids have written a PHP -> C++ converter to speed up a lot of their pages called HipHop:
http://en.wikipedia.org/wiki/HipHop_for_PHPWhich then compiles that down to native code, like, y'know, the rest of the world uses.

So, I don't think Google need to worry unless Faceaids completely ditch their tech team and hire some folk from Google.
