Twitter Developing Location-Based API
adeelarshad82 writes "Twitter developers are now working on a location-based API that will provide accurate information on your whereabouts. Developers will be able to add latitude and longitude to any tweet. The option will definitely be opt-in. Folks will need to activate this new feature by choice, and the exact location data won't be stored for an extended period of time."

Could have been one of those... and I'm sure there are others.
Maybe the cause of your surprise is that you're trivializing things that are actually quite important.
By making Twitter accessible via a web site, the effort required to follow a feed went from (minor, and slightly technical) to (nada). With something like Twitter, which is of only marginal value to most people, I'm guessing that using it needs to have just about zero degree of inconvenience, or else people just won't bother.
Can they add a URL a la tinyurl.com/bit.ly/etc instead/as an option?
