What a clueless site. They rank Chrome OS's chances as 'Sketchy' - clearly they have no idea what's going on in the education market right now. They also included a bunch of things shut down ages ago to pad the numbers.
At least Google has been good (so far) about providing plenty of warning when shutting down existing services. Can't say the same about $RANDOM_STARTUP, where the notice period is often "end of the current month".
At first I thought it might be an useful site providing all annoucements and warnings in one place.
But the copy on this website sounds like a lame attempt on black PR. Especially the part "Don't buy before they die!" made me cringe. Am I supposed to buy after they die or what?
Also those descriptions that are supposed to be substantiations of the rank often lack... well... substance.
The point of this exercise isn't to suggest that Google is failing or on the verge of death itself (and I don't think many respectable people would make those claims). It just mocks the fact that they inevitably shut down a good portion of the (typically free) services they offer, and provides some warning and insight for people who are considering using one of these services in the long term.
