I agree with Tonewalker completely.
MS has made a truly great product in SWAY, but until it has options for detailed analytics it's just for very novice or home use.
As others have noted, and we agree, Docs.com is an option, but it wraps the sway with a header and left-menu which detracts from the simplicity
of the sway, and confuses readers with more "out of context" menus.
So Docs.com really is not a realistic option.
Since MS has comprehensive analytics for many other products, hopefully this is easy to add in the near future.
Until then, we'll just keep using the simple - easy to use other great options that provide great analytics.
We'll check back in 6 to 12 months.
Cheers
