I'm also a little surprised they're raising prices. I figured this monthly revenue was practically nothing on their bottom line, and that they would prefer to keep users on their platform for network effect reasons.
Their chat product also kinda sucks. Ever tried searching your hangouts for a nugget of information? Generally when I think I've typed something in hangouts, I do a search, find absolutely nothing relevant (despite knowing it's in there somewhere), give up, and just check another source.
