Another advantage of racking into foam is it would seem to keep oxygen contact with the beer to a minimum. Of course, there is something (what-air? anyone know?) in the foam bubbles, but logically it seems better as it covers the top of the beer as it's racking. Or am I just passing a giant starsan brain fart?

The foam is filled with trapped air, so I reluctantly vote for the brain fart...

Cheers!

wouldn't the air be kind-of filtered so to speak, because the acid bubbles would kill the things moving in the air?

But it is not the organism in the air you are worrying about, it is the O2 that could cause oxidation. I don't give a **** about worrying about that, it 99.99% of the time will never matter

<- me, as I have had a few homebrews and a couple of afelwiens

That’s funny because every time I rack into a keg (or carboy) it looks just like that. I get as much liquid out as I can and sometimes even let them sit for 20 min so the foam will go down… it’s kind of a pain to see, through all that foam, where you’re at when filling a keg.

Yeah...I learned this the hard way the other day when I could see before I closed the lid that my apfelwein had gone up past the gas dip tube. Hooked it up to a shot of CO2, then hit the poppet to purge ---- apfelwein in my face and on the ceiling (and the walls, and the fridge, and the ceiling fan....)

EDIT: pin-lock keg, so I don't have the pressure-relief valve on the lid.

Nitpick on:
You don't "clean" with StarSan, you sanitize with StarSan. Prior to using the keg (and if possible between uses), you should first CLEAN the keg with PBW, Oxiclean (free), or some other cleaner. This (cleaning) should be followed by a good rinse to make sure you get all the pbw out of the keg and bev/gas tubing, etc. Then you do the StarSan and don't fear the foam.

I actually keep a keg full of Star San which I use to do quick sanitizing of beverage lines, etc.
