Example the Host in Amber Waives of grain gets a good description of the Matrix Sculpting, but I was left with the Impression that the only Personas wandering around in there were IC and Spiders.
The Castle themed host in season ....6? The abandoned duplex, the two missing families...start of the Alter Boy story arc... whatever that one was. Again, nice Maxtrix sculpting, but just window dressing because there was just IC in there.
I'd have to flip through more missions, but active hosts with actual "Typical users" would be nice. Maybe even ones that are handing out Mark Invitations? The CMPs have a few good examples, mostly when you're hitting Hotels for some reason. But I think even in the Sin City series in Vegas one of those had a "Secret Security Host" or some dang thing, that was just a plot device to put the things the PCs wanted to hack behind another layer of Security. Sorry, can't recall the specific CMP.
Anyway, description of the sculpting and what some of the Personas are doing, what the Avatars look like, Hosts that are being used by people to do stuff. Because they should be. Hosts cost a lot of Nuyen (I would think) and should be full of activity. Otherwise whatever is in the Host, should just be kept offline. Let wage slaves walk on down to the secure room and hand in the updates on a chip, or whatever. Run the security through land lines into an old school room full of monitors. I would think a couple miles of cable would be cheaper than a host, and far more secure.
Hosts should be busy. Data is only good if it's being updated constantly and used by some other process. Customer Service Agents (digital and human) should be having conversations and manipulating files. Researchers should be updating data and running simulations. Security should be flipping through the CCTV Channels. Customers should be interacting with other Persona or files, or just hanging out in some cases if it's an entertainment sort of business. You can totally enter a Host in AR. I would suspect that it's pretty common for office workers and most customers to do just that. Unless the corps are springing for full on recliners for their wage slaves. Hosts are Noise free and accessible from anywhere in the world. Unless it's a secret black site silent host, it should be poppin'. Otherwise it's not worth the Nuyen.
