Twitter is on the verge of rolling out its Geolocation API (actually, it's already partially rolled out ). That feature should be a boon to location-based services which can now send their location information back to Twitter and vice versa. But these locations will just be coordinates, it won't be like Foursquare or Gowalla where you check in to actual places to tag your location. A new group aims to merge the ideas. HashCeratops (yes, that's really the name) is a group being led by Buzzd , the service that finds hot places in cities based on other location services. One main feed Buzzd looks to for its data is the Twitter stream. The problem is that without a standard for naming locations, it can be hard to parse tweets to find out exactly where people are. Hence, HashCeratops.
