Sococo was used across the whole organization of 30 members as a way of communicating with staff from a virtual office. Rather than using a phone line, we would communicate through Sococo. It also shows the availability of staff members and who is in the office.
We were required to sign into Sococo daily and update our status of availability (whether we're on lunch, in a meeting, or out of the office).
Sococo solves the issue of limited social connections in a virtual organization - we are still 'visible' to each other, and it was easy to arrange meetings or discuss things with quick 'office' drop-ins. I liked being able to know who was in the office if I had to handle a quick issue or even arrange a last-minute meeting. I also liked how I could see if a staff member was in a meeting with another. It brought visibility and accountability across the whole organization.
