Does "NASA" actually look weird to anybody? That's how NASA themselves write it... so do you Brits think that everything NASA publishes with their name on it looks weird?
I say defer to however the organization in question writes it. That should surely lead to the least confusion and weirdness. It would certainly help UK news organizations with consistency:
In logos I agree but in normal writing it always looks like unwanted emphasis too me.
I think there's a cultural difference here, USAian papers kept up the many founts with underlining, etc thing long after it had become unfashionable in the UK.
The norm is the norm - whatever you're used to.
...which is what my previous post was supposed to highlighting. Somebody took it personally :-(
