Instagram’s location data can be a privacy nightmare but it also allows you to check out what other folks are taking photos of nearby.

If you’re on vacation and want to see some stunning photography in the same place as you, it’s just a click away.

Here’s how to find Instagram photos of nearby beautiful locations, to inspire you on your own journey.

Checkmark, the supper-slick location-aware reminders app for the iPhone, has gotten a feature bump in its newest update that almost (almost!) makes it a new app.

And if you don’t already have Checkmark, then shame on you — the $2 app not only makes location-based reminders on your iPhone way easier and way better than the built in reminders, but it also works on your iPad.

Instapaper just got yet another update (developer Marco Arment seems to be on roll these last couple of months) and it brings a very neat new feature – when you arrive at any chosen location, Instapaper will automatically update your articles in the background. This should mean that never again will you be without your latest saved articles when you rush of to catch a bus.

Trying to get somewhere in a hurry? The folks at Apple figured this might happen, so they built a very neat feature into OS X Lion to help you see a map of any address you’ve been sent via email, or encounter in a web page or document. No copying and pasting required.
