In the Virtual Holland Village I found eight people apparently at work. Two were standing on a commercial property of some sort, one was building something, and three were chatting at a "direct marketing services" place. A fourth joined in and a fifth was at a distance, trying out different textures for the floor of the place. They were all part of the marketing group.
Another person I found sitting on a fence (away) had as his profile picture a reproduction of a nearby bulletin board. I couldn't read it but it looked like a music merchandising enterprise.
I don't have a category for "at work", but since I'm looking for social activity and here I found live humans not really available for socializing, I'll call this Chilling and IM-ing.
This visit happened at 12 pm SLT, Thursday, August 13, 2008.
