While this is a great tip for breaking up in-game writing like in books, and for some special emoting circumstances, I would like to take the opportunity to remind everyone that individual emotes are not supposed to need to consist of a large number of lines. If you can emote quickly enough to include a few lines of descriptive flavor text along with your speech and action, and you want to break up some of the flavor into chunks, that's perfectly fine, and this may well be what's being thought of here. But that aside, people should continue to keep in mind that emotes should flow back and forth between player characters in a relatively realistic way that allows them to react to one another in more or less real time.
This isn't to say that people may not need to slow down the overall pace of roleplay sometimes -- there are various perfectly legitimate reasons for doing that, and we've seen some great use of the xcard system for these situations. But what we still DON'T want to see is single emotes that incorporate multiple actions or conversations in way that is not realistic. A single emote should not address several people sequentially, so that you're having several different conversations with multiple others in the same emote. A single emote should also not incorporate multiple actions that would realistically take a few minutes to perform sequentially and/or would normally allow for other people to act or react in between them.
Can you, in one emote, nod to Akil, say hello to Samia, and pick up a delectable pickled egg from the galley table in one emote? Sure thing. Should you, likewise in one emote, say hello to Akil and good afternoon to Samia and ask how Samia's sick aunt is doing, pick up a pickled egg, insult Cook Alif's mother, walk over to the hearth to warm your backside, tell Sharif you like his hat, and then decide to throw your egg at Akil because you've suddenly realized how annoying he is and that you never liked pickled eggs anyway? No, no you shouldn't (and not just because it's a deplorable waste of precious pickled eggs).
In situations like that last one, converting a single one-long-paragraph emote into a single multiple-short-paragraphs emote is still not breaking up your emote in a real-time way. All the lines are still being output at the same instant, which doesn't give people a chance to respond to each action in a realistic, more or less in-the-moment way. This runs contrary to the norms we've discussed wanting to see, and which for the most part we definitely have been seeing. Again, this doesn't mean that people need to write super-short emotes all the time, just that individual emotes should not consist of multiple actions or conversations which would realistically take place sequentially over a short period of time, not all at once.
Sorry to derail the tip, but I thought it was a good opportunity to drop a reminder, and also clue in our new players who haven't even had a chance to learn the culture yet!
