Location Wars

So, the Location Wars have begun in earnest - Facebook and Twitter have joined Google in launching location based services.

NYT on Facebook:

Starting next month, the more than 400 million Facebook users could begin seeing a new kind of status update flow through their news feed: the current locations of their friends.

Facebook plans to take the wraps off a new location-based feature in late April at f8, the company’s yearly developer conference, according to several people briefed on the project, who spoke on condition of anonymity because they were not authorized to discuss unannounced services.

In preparation for the introduction, Facebook updated its privacy policy last November. The new policy states: “When you share your location with others or add a location to something you post, we treat that like any other content you post.”

At that time, the company also offered some foreshadowing of the new feature: “If we offer a service that supports this type of location sharing we will present you with an opt-in choice of whether you want to participate.”

The temptation to do opt-out is going to be very strong though.....on past performance it wouldn't be surprising is that "opt-in2 promise is very liberally interpreted,

Twitter too is gearing up - TechCrunch:

The service has just turned on geolocation on its website today for the first time.

While Twitter’s geolocation feature has been live through its API since last November, there was no sign of integration into the main twitter.com site until now. As you can see in the screenshot above, for tweets tagged with location, right next to the source of the tweet there is a location placemarker. When you hover over it, it turns blue, and clicking on it brings up a little Google map showing the location that tweet was sent from.

You can see these maps as overlays both on individual tweet pages, and on tweets in your main stream. In some cases, depending on how Twitter geolocation API is being used, it looks like place names are even passed through to Twitter.

Timing is of course to coincide with SXSWi, where Location startups Gowalla, Foursquae and who knows how many others are trying to get that lifegiving buzz going (Buzz - now there is another location ploy) in the biggest geekfest on the planet. SXSW lends itself to this sort of thing as thousands of hungry and thirsty (for knowledge, natch) geeks seek their networked friends for meals over the 12 or so blocks of Austin Olde Town.

What can we say that we haven't said already (just search for "location" on the blog) except be careful - Location based services play faster and looser with privacy than anything that has gone before.
