Twitter has allowed users to tweet their location via its Places feature for a while now, but now it appears that Twitter is considering allowing businesses to claim their locations, as they can on Google and Facebook.
Twitter would need to contend with the same thing that Facebook confronts: the presence of a Place Page and a Fan Page (in this case a Twitter Place and a business' Twitter account). The only claimed location on Twitter right now is apparently Twitter HQ, has been "claimed" by @Twitter.
The "claiming" of Place pages could be a sign that Twitter is getting serious about competing in the geolocation space currently dominated by Facebook and Foursquare. It could give businesses a new avenue to promote themselves on Twitter, and it could lead to new revenue possibilities for the microblogging service.
Twitter provided a statement about the status of claiming Places on Twitter:
Claiming Twitter Places is not available at this time. We're experimenting with a variety features. Allowing businesses to claim a Place is a natural thing to consider for the future.
