I get bored by dialogue without context. When I'm after spoken word roleplay I dip into LOTJ (or one of the other hack and slashy type RP MUDs). I'm ashamed to admit that if someone is using just "say" I find myself making my way out of the scene, solely because without context I have nothing to go on (Note: This is a weakness of
mine, rather than a fault of those who use "say" as their primary roleplay command; it's just not my style).
I'm not a fan of purple prose, but I am a huge, huge fan of emotes that have more content and context than dialogue. I'm not here to write out conversations I could have by text message, nor am I really here to read them (this sounds way meaner than I want it to; again, I should point out this is a fault of mine, different styles for different folks -- rapid fire RP is no less valid than any other variety). Generally speaking, a long emote in and of itself does not a quality emote make, but when somebody is tossing out a novel and it's evocative, excellent stuff, I really couldn't be happier.
I think our emote standards are 2 lines cut at 80-characters per line to be credited for RPXP. With very different emoting styles on TI, one favoring brevity and the other depth (and really, all else between), I think two lines is a pretty fair middling point for emote and rpecho.
For hemote, I am in 100% agreement that it should be a "by use" RPXP bonus, similar to think. If it's a few words, that's probably enough for something the people in the room might not notice.
Edit:
Oooh. The reddit poster actually hit the nail on the head, I think, and was similar to something Geras said above:
