A lot of us are still adapting to what the web portal enables in Ares. It's so different from what we've done in the past.
'Whaaat? A player can participate in an on-game scene without logging in?!'
'So I can do my entire scene with someone much like I would in GDocs....and the log is already good to go?'
I'm trying to take it a step further (at least for me):
@Paradox has a difficult schedule for playing and he's been dedicating what online time he has to providing for the players (be it working jobs, running scenes, or just being present). I am a firm believer that staff should get to play, too.
Additionally, I have some players in non-US timezones (Australia, UK, and Norway off the top of my head).
Paradox and I happen to have a very similar schedule right now, so most 'live' scenes are going to be run starting around 7-9p CST. That's not ideal for everyone. I'll be able to run some on weekends earlier in the day, but even so.
As such, I decided I wanted to try running a plot entirely through the portal. I made certain my 'testers' understood that it may be a full 24 hours between poses sometimes (between RL schedules, differing timezones, etc.) and that the scene will be considered to have occurred (game-time) once it's completed (for example: if the scene began on the 8th of September and finished on the 20th of September, they'd consider it as having occurred on the 20th of September).
The reason for this is multi-faceted. Players can fold in 'current knowledge' instead of having to pretend a scene on the 10th hasn't happened because they're still RPing the 8th. Players don't have to worry about 'oh shit I got badly injured......but I RP'd a scene today that-'
I think we can all understand the logic behind that! 
I'm only a few days into the first plot run this way, but I have a few observations so far:
Pros-
- As the ST, I have more time to dedicate to my responses. Instead of being pressed for time after calling for an Alertness check, I can take my time to craft customized responses to each person ('Because of your background in X, you see...' 'While gazing off in <direction mentioned in PC pose>, you spot...'
- I can spend time between ST poses/actions considering each PC, what they're doing, and how can I craft this to be poignant to them?
- I have time to adapt my plot outline as necessary ("OK, they skipped past that which means this encounter doesn't happen now, but happens over here instead with this adjustment...")
- I can take more extensive notes.
- Players who don't otherwise get to be involved in plot have an opportunity (and they may also play with people they otherwise wouldn't!).
Cons-
- I have to take extensive notes (this is love/hate: having notes is fuckin' awesome, but if I forget to notate something the likelihood of forgetting it later increases).
- Players might become bored and lose interest because they're waiting so long between actions.
Learning Notes-
- Absolutely encourage players to give you permission to roll for them. Ares makes it easy to roll for someone*, so getting this permission will help expedite things.
- Don't be afraid to 'guide' people a bit. This is something often needed in all plots (how often do you feel like your players are meandering and waiting for someone to make a definitive decision? In case of asynch play: make it for them if they're waffling). This also includes 'tell someone what you want them to roll.' Make safe assumptions. 'I mentioned a computer present, so I'm going to ask Bob-the-Hacker to roll Computers.'
- The sort of anxiety that comes with running scenes is gone. I'm able to take my time, focus, and think things through (vs. the pressure of 'oh god everyone's eyes are on me!' stage fright sensation). This may mean this is a method that would be fantastic for newbie STs or those who are often too nervous to ST (but want to nonetheless).
*I will note that in the current iteration of the web portal, you cannot roll for a PC. You can roll for NPCs (providing the total ability score), but not 'roll Bob's Computers.' The game does allow this, so my workaround is to scene/join the scene in question on the game and make the roll there (roll <name>/<skill>). It'll still apply it to the log, just not as convenient as doing it from the web portal when you're already there.
All that said, I wanted to share my concept and what I've learned after just a few days of trialing the idea. I'll likely update this as time passes with any other observations / learning opportunities, but since I have players who are really into the idea: maybe you would too.
