To learn how to deal with this new openness, I met with Tom Coates at Caffe Centro (37.781694 °N, 122.394234 °W). Coates started Fire Eagle, a sort of location clearinghouse: You tell Fire Eagle where you are, and it sends that info to a host of other geoapps, like Outside.in and Bizroof. Not only does Fire Eagle save you from having to update the same information on multiple programs, it also lets you specify the level of detail to give each app—precise location, general neighborhood, or just the city you're in. The idea is that these options will mitigate privacy concerns. In addition to this, as Coates puts it: "You have to have the ability to lie about your location."
Any good social geoapp will let you type in a fake position manually, Coates says. Great news; I didn't need to get busted for missing meetings—or deadlines—ever again.
I was starting to revel in the benefits of location awareness. By trusting an app (iWant) that showed me nearby dining options, I discovered an Iraqi joint in my neighborhood that I'd somehow neglected. Thanks to an app (GasBag) that displayed gas stations with current prices, I was able to find the cheapest petrol no matter where I drove. In Reno, one program (HeyWhatsThat) even gave me the names and elevation profiles of all the surrounding mountains. And another (WikiMe), which displayed Wikipedia entries about local points of interest, taught me a thing or two about the San Francisco waterfront. (Did you know the Marina District exists largely because a land speculator built a seawall in the 1890s?) These GPS tools were making me smarter.
And more social. While working downtown one day, it looked like I was going to have to endure a lonely burrito lunch by myself. So I updated my location and asked for company. My friend Mike saw my post on Twitter and dropped by on his way to the office. Later, I met up with a couple of people I had previously known only online: After learning I would be just around the corner from their office, we agreed to get together for coffee. One of them, it turns out, works in a field I cover and gave me a tip on a story.
But then, two weeks into the experiment, I bumped into my friend Mindy at the Dovre Club (37.749008 °N, 122.420547 °W). She mentioned my constant updates, which she'd noticed on Facebook. "It seems sort of odd," she said with a note of concern. "I've been a little worried about you. I thought, 'Wow, Mat must be really lonely.'"
I explained that I wasn't actually begging for company; I was just telling people where I was. But it's an understandable misperception. This is new territory, and there's no established etiquette or protocol.
This issue came up again while having dinner with a friend at Greens (37.806679 °N, 122.432131 °W), an upscale vegetarian restaurant. Of course, I thought nothing of broadcasting my location. But moments after we were seated, two other friends—Randy and Cameron—showed up, obviously expecting to join us. Randy squatted at the end of the table. Cameron stood. After a while, it became apparent that no more chairs would be coming, so they left awkwardly. I felt bad, but I hadn't really invited them. Or had I?

There were also missed connections—lots of missed connections. Apple doesn't let applications from outside software makers run in the background on the iPhone—for a third-party app to work, it has to be the one currently on the screen. Apple says it does this to prevent random programs from sucking down your battery and degrading your phone's performance. As a result, iPhone location apps can't send out constant updates. This means that people are often showing up where you were, rather than where you are. On a Friday afternoon, for example, I posted an update looking for nearby friends to share a postwork beer downtown (37.787229 °N, 122.387093 °W). A short time later, I heard back from my friend Lisey, who wanted to meet up. But I had already moved on to Zeitgeist (37.770088 °N, 122.422194 °W), a beer garden in San Francisco's Mission District. I again updated my location. But the place was packed, so I decided to split and headed to Toronado (37.771920 °N, 122.431213 °W), a bar closer to home. Just after I left, I heard from Lisey again, who was now on her way to the Mission. I had accidentally dodged her twice. I later discovered that two more pals had shown up at Zeitgeist looking for me.
One way around such snafus is to use the Google phone, T-Mobile's G1. Unlike the iPhone, the G1 lets programs run in the background, so you can launch location-aware apps and keep them humming while you do other things—check email, make calls, take pictures—or just drop the phone in your pocket.
