Definitely interesting. As other commenters have mentioned, a spike in status and experience updates definitely often signifies something is going down. Another one is recommendations. When one person suddenly is getting 2-3 recommendations from colleagues, they are usually on their way out. If a lot of people from the same company is getting recommendations left and right from each other, the company is either going down or there is serious downsizing imminent. Very interesting side effect of sites like LinkedIn.
