I dunno... that article you linked has this part in it:
"Springpad co-founder Jeff Chow, who previously worked with Janer at Third Screen Media (acquired by AOL), is joining Google in Kendall Square, along with Springpad’s top four engineers:"
Sounds exactly like an acqhire that somehow instead became a poach. And a pretty rip-the-heart-out poach too. I can't think of any start-ups that could survive that kind of talent loss. I envision some upper-management person suggesting buying SpringPad, Google-execs veto it, but said upper-management person secured the funds to poach out the core.
