How do you drink whisky yourself?

Heavily, though it does give a uniquely nasty hangover when abused

How much do you pour at once and in total on average?

About 3 fingers

Undiluted, diluted, ice?

I've always taken my drinks on the rocks, even my coffee, it's just my thing. Purists will argue that I'm not getting the full effect, like I can't taste the goat shit from 1898 that got left in the peat, et al, but that's bullshit

Which type of glass do you prefer and why?

Any short tumbler will do, flask on the golf course

Where do you get info about the stuff you might be interested in online?

Just buy something and try it. There was a guy named Michael Jackson (not the King of Pop) who the definitive guide, in my opinion. You seem to be ahead of the curve already, so do what you like.
