Another day, another leak from Google. As The Next Web reports, a note-collecting service called Keep was accessible on Google Drive for a short period of time last night -- and if your short-term memory is a bit cloudy, Drive itself got leaked in a similarly bizarre fashion before getting official last year. 1E100 had initially found source code, images and various links that seemed to point to Keep, which apparently went live soon after. Interestingly, while all of the links point to error pages, one redirects to a specific, unresolveable app url on Google Play. Android Police was able to snag some screenshots of the web app in action -- albeit disconnected from Drive at the time -- noting that it's reminiscent of Mountain View's late Notebook service that was killed in '09. Whether the likes of Evernote will have to worry remains to be seen, but the added functionality to Drive will certainly be appreciated -- now, how about letting us get at that Now app for iOS?
