Which of these features would be useful?
What are some of the privacy, surveillance and social exclusion issues that arise from these features?

The only feature on this list that would be actually be useful with minimal infringement on privacy would be the ability to view information/reviews/comments friends (or even public comments by strangers) people have left for places such as restaurants. It could be a digital graffiti scenario. While this may produce the problem of showing others where you physically spend time if users keep it to their friendship groups it should be a safe experience.

The rest of these options give out way to much of your information and allow people who are so inclined to track/stalk you.

How does the use of location-aware applications change out experience of the world?
-e.g. Facebook check ins or location tags, foursquare
– Is location-awareness a momentous development or merely a passing fad?

It is an unsafe development, there is very little a user gets out of it, meanwhile there is a lot to be gather from predators and companies wanting to market products to you. The idea of targeted marketing seems nice, the increased opportunities business have to advertise to you hardly seems worth it when compared to the amount of times I’ve met up with someone for an impromptu coffee because my social media application told me they were in the area.  I would rather not be marketed to at all.
