One Big Ad orgy is it.

That holds in this country, however, content from the BBC website is ad-ridden when viewed from outside UK.
Bank Robber: "I don't have the wherewithal to steal as much money as I want to, so you can worry a bit less about me"
Now I have reason to get one.
what? a tat(too) or some tat (i.e. an Apple watch)?
not really, the "lifting capacity" is from the difference in mass between lifting gas and surrounding air. Air is ~29 g/mol, so the ratio of lifting capacity of H2:He is
[(29 - 2) / 29] : [(29 - 4) / 29] = 27/25,
works out at 8% difference. The containment vessel's weight is typically more significant than the gas itself in a lighter-than-air craft.
Balloons with He3 give only 3% more lift than He4, lunacy!

G+ suits me fine, I have no friends IRL either.
You insensitive clod. People sometimes go on at me about being antisocial, I think they're being overly judgemental in implying it's a bad thing.
No [r] way!
Kenya imagine a worse country-name pun than that?
Oman that's awful!
Mars' atmosphere is
"For all practical purposes" is not correct. The thermal conductivity of a gas is near-independent of pressure down to very low pressures, until the mean free path of particles becomes large compared to the distance to the solid where the heat gets dumped.
20mBar and the MFP is still tiny.
You need a pretty good vacuum (10^-4mbar or so) in a coffee flask otherwise it doesn't change a thing.
