Hey Costales,

I'm not entirely sure where the insult comes in, we are having a
technical conversation here.
Also note that I do not say that apps do it wrong, it might very well
be any other layer in the stack that
fails to handle the data correctly.

Sure, most of them valid and I'm aware of them, fixing them one by
one. Not sure where the disconnect
comes in, but we talked about exactly the points mentioned here last
week in person, and I got the impression that
we were in agreement.

Cheers,
