Yeah, one of things I've been curious to see is how the two services are going to slot together.

Long term Flickr Pro user (signed up 2007) and when my Pro sub expires a year from now there's some compelling reasons to dump Flickr and migrate to SmugMug - not least that SM's had literally anything done with it in the last few years, while Flickr's just got clunkier and clunkier (but also that there's a bunch of old, not-good, photos that I don't really care about on there).

The quality of the "community" on both Flickr and 500px makes the de-prioritisation of the same on SmugMug an advantage too - there's way too much spam on Flickr, although even that's dropped off over the last few years.
