There are also times where there are more Snaps than Waves for a given period, too. For instance, I just counted 27 Snaps to 7 Waves in the last four hours.
I see, it's good that we have these moments, I think it might be something to do with the time, for example here in Brazil when it's around 8 or 9 at night, I notice that the flow slows down, so it might be dawn in other countries and that's why people disappear from the snaps.
I confess that lately I'm not that active on snaps, but I haven't gotten that impression yet.
I think that any action that can improve the environment is always welcome.
Snaps is quite a bit newer, and the other two have large, tight communities while PeakD is much more broad ... some of this is the requirement of time, and some of this is indeed the need for @peakd to promote it more.
