Increasingly systems are personalizing how and what they display to people. In many cases this is great as it makes the experience much more relevant. However I find that there are many times where this is not so great. For example, google search has been for quite a while now returning results that are based on your geolocation determined from your IP address. If I am looking for a restaurant, then this may be good. But if I am searching for news or some other information then this is not that good at all. No longer are you able to accidentally find something interesting which even though it may not be located near you is still very relevant to your interests. The digital world of all places should not always be bound by our physical location.
This gets worse when your IP address may actually be wrong. I worked for a company where we had a global network. I could change my network proxy to appear as if I was in the UK, when I was really sitting in Chicago. This at times could be amusing, but more often it made us aware that searching for the exact same term provided differently ranked results depending on where google thought we were located. I am not sure there is a solution here as the benefits of location relevancy seem to outweigh the benefit of serendipity. But I do have a sense of loss or nostalgia at times for days when I would find interesting articles from people in other parts of the world.
