Touch-to-share was a grand concept introduced with the TouchPad, Pre3 and Veer to be able to share data between two devices by simply tapping them together. Unfortunately, the initial implementation of TTS only allowed you to share web page URLs, and it never even came to the Veer in the promised software update to webOS 2.2. So, unless you have a Pre3 and a TouchPad (or two TouchPads), you are seemingly just limited to sending website address to and from the browser app.
It turns out, though, you are not just limited to the browser app to share these website addresses. We have already seen Zap Photoshare utilize touch-to-share to send the website address to view photos on a second device, and now forum member kmoll3ster noticed that the TouchPad's Facebook app also includes a Touch-to-share feature. If you are viewing a photo from within the Facebook Tablet app and then Touch-to-share with another TouchPad or Pre3, the browser will launch and load up the facebook.com website for that photo. Not exactly an extremely useful feature, but one that exists nonetheless and only for photos, as it does not work with other articles or posts. And be aware that this is a one-way feature as it's only built into the TouchPad's Facebook app and not the smartphone version, although you can use App Tuckerbox to install Facebook Tablet on your Pre3 to send it from a Pre3 to a TouchPad.
Thanks to kmoll3ster in our forums for this tip!
