The ever-readable Mat Honan on how Yahoo didn't get Flickr right, even though it was poised to do so in 2005 with social sharing. Why? Corporate Development. (Thanks @TehGreatGonzo for the link.)

What's remarkable is how two companies dominate these statistics so thoroughly.

Photographer Thomas Hawk: "Flickr asked me if I wanted to apply it only to photos going forward, or also to images that I’d already geotagged. I told flickr to go ahead and apply this setting to all of my past and future photos — which included a thumbnail of the photo I linked. So now when you go to this photo on flickr, indeed, the geotag seems to be removed from the photo page for the image.<br />
"Except that there is one pretty major security hole.<br />
"Although the geotag information is indeed pulled from the flickr photo page, ANYONE can potentially still get your geolocational data simply by downloading the original sized file and looking into the EXIF data.<br />
"This only seems to apply to images that were geotaged at the file level (i.e. by you or your device/phone, etc.) and not photos geotagged using flickr — but still, with cell phones and software that auto geotag things, you could easily be lulled into a false sense of security on Flickr when you should not be."
