I'm super flexible.
I find that I tend to accommodate myself to my partner's times, but this can have deleterious consequences. For example, if you take between 10-15 minutes to pose, then I'm going to take around 10 minutes to pose. Because while I'm waiting for you to pose, I'm going to do something else (watch something fullscreen, read a comic book, check out a blog, whatever) and I'm not going to just stop every minute to check and see if you've posed. I'm going to let the scene finish, or finish the issue, or the article, or whatever.
If you like big flowing paragraphs, you're shit out of luck with me for the most part. Oh, sure, if you're posing flowery long stuff, you'll get it out of me more often than not--but by and large, my poses are anywhere between a single line and 6-7 lines. I don't get longer than that unless there's a real need. Usually I stick around somewhere between 3-4. This isn't on purpose. It's just how it comes out. The only time I really concentrate on how I want them to seem is when the writing style is meant to convey something about the character--I played a character who was based on Hemingway recently (again, shocker right?) and his poses tended to have very little exposition and they had short, to-the-point sentences. He liked to talk, but he didn't talk overmuch. This was because that's how I wanted him to come off. In contrast, I played a character who didn't talk at all, and refused to use sign language or lettered communication--he was one of my most popular on The Reach. Everyone who bothered to mention it told me they loved playing with him. I had Interdisciplinary Specialty: Body Language, and I posed the hell out of it--but it was still just 3-4 lines a pose. He got his point across. I know at least one person found him frustrating, but they just didn't play with me much. No skin off my nose.
I really like it when dialogue takes the front seat, in contrast to some other people here. Some of my favorite scenes have been pretty much just dialogue--I even have had some partners with whom I could drop to just dialogue, without any dialogue tags even. Just the speech--back and forth--bam bam bam bam--rapid-fire comments, entire conversations that happened almost in real time. It's only possible in 1-on-1, of course, but still!
I hate pose order. I understand the need for it; I still hate it.
I also know some people fistshake at me because I pose too fast ( @Sunny, @Gingerlily). #sorrynotsorry. 
If I am having a lazy Saturday or Sunday devoted to RP, I can do the same scene for hours and hours. I once had a scene on a comic book MU between Superboy (me) and Nico Minoru that lasted eight hours and by the end we were both like--you know we should probably stop because we need to eat and maybe do other stuff today. Not because the scene couldn't continue. But in general--in general--I largely prefer my scenes to last around 2-3 hours; and if they can be shorter? Great. I see scenes as scenes, not as long drawn out interactions. Start the scene with something significant, end the scene when something significant concludes. I hate (and this happens a lot, and that's okay, but I still hate it) when scenes sort of peter out. I love scenes that start almost in media res and end before they conclude.
Devlin and Phineas start a scene on a plane--they jump out of it! WHEEE! They land in a field of ostriches. Oh shit! They run around for two hours of RL time, having fun-finally they escape the ostriches. But they need to get back home! Oh, look, there's an expensive car on the road with no driver and Phin says, "I just found our ride." End scene.
Maybe we pick up with them already half-way home, speeding down the highway in their stolen car. Maybe we just assume that happened and tell the story to someone else later on. But the scene was the ostrich field. Not the car ride. Two separate scenes. If more people were able to cut scenes this way, I would be so much happier.
In direct contrast, in plot scenes--omfg, storyteller, move it along. A "plot event" does not need to only comprise itself of a single scene that happens in a single place. Fade in! Introduction! Crossfade! Next scene! Crossfade again! Next scene! Crossfade to climax! Fade out! Storyteller goes to bed, and the players play out their epilogue or whatever. Keep it movin', yo.
Anyway, rant.
As for time management: man, fuck continuity. Fucking television shows don't give a shit and millions of people watch and enjoy them. Don't give me this "but I don't know if my character can do this because this and that" crap. Either keep it nebulous, or make sure you know what the fuck your character is doing all the time. Argh. So many scenes that petered out into nothing because half the people RP a lot all over the place and the other half don't--so some have a lot of conflict and others don't. /tableflip.
Also, you wanna make me happy? Like, really happy? Storytell. Not events, not PRPs--just storytell. Introduce complications. Make it weird. Have something happen. Man, I will help you out. There is this misconception that all great scenes have one ST. No, many scenes have more than one. I will sit at my chair and roleplay with you all fucking day if you storytell with me. If you collaborate and make the setting come alive with me, and I see this so little that I barely do it anymore, either. A bar fight should not be an event, guys. A bar fight should be a random backdrop in an otherwise random scene. Karaoke night should not be a scheduled +event; karaoke night should be every Tuesday, from 7EST to 11EST, come rain or fucking shine, for anyone who wants to show up, which sometimes means two people and sometimes it means thirty.
God, karaoke. The first public MU I ever played in was Devilshire, a Buffy MUX. Shoshana Swann had a place called The Penalty Box and they had karaoke night there every Tuesday, like fucking clockwork. One of my alts worked there. Sometimes I participated. Sometimes I didn't. But I knew that if I showed up in that build on a Tuesday night, the roleplay would have a backdrop of karaoke. I just knew it. And it was fucking awesome. It didn't have to happen every Tuesday. Shoshana wasn't even there half the time--sometimes it was just players, none of which had alts working at the business, who still did karaoke RP on Tuesdays, because that was the activity there on that day. And sometimes Tuesdays had a lot of people and we used places code; and sometimes it was just four of us and we injected some plot--vampires loved karaoke night and we loved staking them while someone sang Voltaire's Vampire Club into the mic off-key. Whatever. It's Buffy.
Anyway. Yeah. I went completely off-topic, I think. Sorry.
