I'm in the camp that thinks the occassional "thoughtful emote" is useful, particularly in cases where the emote conveys the subtetext of the spoken words. To use a purposefully 'bad' example:
A man in his thirties say: "Yeah, I am really glad to see you too. *Scowls a bit, thinking back to the last thieves meeting"*
I try to avoid such things as much as possible, but am very willing to give people the benefit of the doubt. It's one thing to simply scowl, or to scowl and write something much longer like
*scowls and stares down at his hands, his eyes slightly unfocused and shaking his head slightly, muttering something under his breath that sounds like it might have been 'eeves'* While the latter is much more specific and neutral, most people do not 'think' that way, and translating your mental perspective to notice only what others may see is difficult. In real conversations, there are HUGE numbers of subtle signs from body language, and even shared context, that get lost in a purely written text. Yes, the challenge of Cantr is to put those cues into well roleplayed text, but not everyone is a writer. My first example may be 'wrong', but it gives me the same mental picture of the scene, mostly.
I'd much rather have entertaining and believable characters who emote 'improperly', than a very few 'expert RP' writers to interact with in-game.
