Best way to create planet atmosphers?

I totally appreciate that, and there's nothing particularly wrong with what you said in the context of how you meant it, *but* those sorts of comments are at best neutral and usually counterproductive.

I can understand your frustration, but it'd be better just to mark the Planet demo as 'not take deadlines at face value' for yourself and let it just happen when it does, without publicly commenting on someone always making excuses. Publicly airing your opinion that giving deadlines is silly because Mustang doesn't stick to them wasn't going to help solve your frustration and wasn't needed for you to be able to ignore the deadlines.

It's not about treading on eggshells, but not making points that don't need to be made if those points aren't positive or won't help solve whatever situation you have those points on. And remember that text is devoid of intonation and thus naturally a lot more 'offensive' or 'antagonistic' than the spoken word. Anything typed is going to be viewed ordinarily in the worst possible light by the reader. Passing remarks can come off as insults to a reader where they'd see them as just remarks if said to them directly.

In the same way internet communication has people use extra communication like smilies, so too must what's being written be considered differently to how it would sound being spoken.

These remarks are intended as a 'heads-up' more than anything. It's best-practice when writing to forums etc. to consider 'why am I writing this and what am I trying to say' before hitting the send button. If there's no constructive answer to the why question it's probably not worth sending.
