Achronos, you miss the point of office small talk. Nobody really cares about you, nor you about them, however, it's a good way to build camaraderie. In this way the team will always be more successful.
For example, George sits in the corner and doesn't talk to anyone, ever. Judy has been assigned to work on a project with George. How should she handle this situation? She needs his input and advice, etc.
Had there been small talk previous to this occasion, Judy would know that George is an avid fisherman, gardener, painter, builder, etc. She could hone in on these unique talents of his to help with the project. Additionally, she would be able to converse with him, in those inevitable moments when you arrive to meetings, and sit around waiting for others to show up, etc. Plus, she would know not to speak up against a, b, or c and cause strife between the two of them.
The only time office small talk is a bummer, is when you have work to get done, and the other person just drones on and on and on. I often find that my cube turns in to Grand Central Station. Since I am sitting at my desk, I am stuck, because the person is actually blocking my way "out". Thankfully, I am at my desk, and if the boss comes around, the other person is visiting me, and not the other way around.
We have a few people who will easily talk for 45 minutes to an hour....even if I turn my back on them to answer emails, etc. It's just amazing.
