Done.

nit: It's a little odd to separate UMA, Rappor, and Variations from one another,
since they're all facets of the same service.  Any particular reason you didn't
choose to group them together?

[amohammadkhan, 2015/09/04 23:03:16]

Yes. By having them separated, the contribution of each one is more clear and it
will help me understand different sources of chatter in chrome more precisely.
My ideal goal was even having more granularity but it was not possible for now.

[Ilya Sherman, 2015/09/08 21:45:25]

Sorry, I see now that my question wasn't clear.  What I meant was: Would it make
sense to sort this list so that these related services are adjacent to one
another?

[amohammadkhan, 2015/09/08 23:28:31]

Sorry I didn't understand first time what you meant. I am not sure about the
relations between other services but I made UMA/Variations/Rapport adjacent.
