Here is a little question, but possibly worth asking:

Is beer foam negatively impacted by skimming of hot break in the early boil and/or filtering cold break in the chilling process?

According to what I learned many years ago, yes it is.  May or may not still be true in light of later research.

  That would make sense, but perhaps it is all a matter of degree?  And so many sing the praises of clear wort transferred from the boil kettle....

Yes, that's true.  Experience is a great teacher, though.

FWIW

I used to skim off hot break, now I let it disappear on its own.
I do beat it back with a spoon if it tries to get out of the kettle.

I love skimming.  It gives me something to do during the boil.   

Can't say that it hurts foam retention because I've always skimmed.  But...I will admit that sometimes I get great foam, foam retention and beautiful lacing down the glass.  Sometimes not so much.  I've always chalked that up to grain bill however.  An example of great foam would be my Stout with lots of Flaked Barley and some Wheat Malt.  My Porter, which has neither, does not.  Is that the reason?  I can't say for sure but it is an easy place to point the finger.

The main reason I carbonate using bottled CO2 is because it saves time.

Have you tried spunding? 

I like to do it in the fermentor prior to chilling and racking to the serving keg (you get better oxygen protection by spunding in the serving keg, but this works better with my schedule) - very quick, nice tight/small bubbles, possible increase in production of foam-positive glycerin.

excellent question, the one i always wonder about but forget after brewday.

also, the layer of oily/thick sludgey stuff that starts to build up slowly after about 20 mins of boil? anyone else? i usually collect it and dump it in the hop spider, but it continues to slowly grow throughout the boil. and i do use a pristine, fully removed of detritus kettle

The head on my cream ale this afternoon.  In this case I have nothing to complain about.

What's the science behind the pouring method effect on foam, independently of the beer.
Eg,
Czech side pour vs
Standard tap vs
Stout tap

If you re-use a glass that had a nitro beer in it, like a Guinness, why is the lacing so distinct, like the previous beer?

I get that a lot, but I don't have Guinness on nitro

There are others.
Intertap has one too.

Was busy at work until late Friday missing this presentation.
Can't find this discussion at AHA site.
Anyone have a lead where I can view?

I missed it, as well, but afterwards I clicked the link for joining the live presentation and it took me directly to the recording.  I definitely found it informative.

I'm assuming that if you don't have the link handy, you should be able to login to https://crowdcast.io and find it.
