What's in your email signature and.. does anyone care?

I just read a poorly written blog entry about email signatures. Despite his writing being boring and disorganized, the writer started an interesting discussion about email signatures. He says that lower food chain types have longer signatures (inverse relationship) while more important people evidently don't have to tell the world who they are. I'm not sure about that, but I haven't put much thought into signatures. I wonder if people do notice them and if they do change recipient's perceptions of the sender. Do people actually feel uplifted by the inspirational quotes sigs often contain? Do they actually get messaged* by the marketing slogans? I don't think anyone's done any research into this. It's worth thinking about.

I don't have a signature but after reading it, I'm going to get me one and add this blog address. I'll let you know if I see any results.
