    I think it has to do with the dissolved gas… Guinness has nitrogen vs carbon dioxide, which is denser

      I believe this is partially true. Guinness has a mix of dissolved nitrogen and carbon dioxide, called G-Mix (some info here and here). Apparently this is typically in a ratio of 75% nitrogen to 25% carbon dioxide, although if you mix your own you can determine the ratio based on your draft setup and the desired outcome. Having the CO2 in there is also is why it tastes less flat than other nitrogenated beers, I think.
