How do you know that it wouldn't be hard to make comments on the progress. I'm sure Scawen should throw around with words that nobody except BBT, Niels and some others can understand but that wouldn't really make sense.
And how do you make a screenshot of physics?
And I'm pretty sure that those screenshots wouldn't cool down the heat and lift up the spirits.
I have another league race before this on Sunday which usually ends at around 19:10 so would it be ok if I joined right after that just to set 2 or 3 laps in quali?
Nobody is "partying" that. We all would love to have more frequent updates, it's just that some people are intelligent enough to have realized by now that moaning and whining doesn't make the progress any faster.
I have no idea how many Mac users there are and I have no idea how many of them are potential LFS customers but I don't think it would be that many.
However, with the new physics coming with a big patch, there will certainly be some articles on some bigger sim-racing sites turning the attention from other sim-racing fans (back) towards LFS. Add to that simply word of mouth as Dustin said and I'd say the number of potential buyers is higher there.
