Ask HN: Google Keep vs. Evernote usage data since Keep's release?

Does anyone know what usage has been like for Google Keep ever since its launch, and whether this has affected Evernote's user base in a negative way at all? (And maybe the others too, like SpringPad and Catch, etc)

I'm wondering because Keep actually made me switch from Evernote, which I loved for a very long time. GK is great for quick note taking, it's sleek and fast, unlike Evernote which began to feel bloated and slow. I don't know how other people use these apps though. There's also the sentiment that Google might shut it down in a few years so they won't use Keep.
