Hi Joaquin :]

In all WMF's "browser reports", the slice classified as "Other" can mean 1
of 2 things:

*1) Ua-parser <https://github.com/wikimedia/analytics-ua-parser> classifies
those requests as "Other".*
In this case, the requests come with a UA that is not recognized by
ua-parser. Probably they are, as you suggest, crawlers, bots or other kinds
of uncommon traffic. This should represent the smaller part of the whole
"Other" slice.

*2) The anonymization algorithm is sanitizing those requests setting them
to "Other".*
Browser stats data is privacy-sensitive, and we can not store it raw. There
is an algorithm that sanitizes all request groups that are too uncommon,
like "Opera 43 on Windows Phone", because they are so specific that they
could be used to re-identify a user. Each one of those groups is really
small, but all sanitized groups together make up to ~10% of the traffic.

We Analytics want to dedicate some time to this hopefully next quarter, to
reduce the percentage of that slice without loosing privacy:

*Also*, I think the term "Other" is very confusing here, because it
indicates that that big 8.8% slice is neither Safari nor Chrome nor Android
nor Opera etc. But, in fact, this 8.8% includes all those browsers, it is
made of all those browsers. In my opinion those requests should be labelled
"Unknown" or "Sanitized" instead.

Cheers!
