Vanity is the background of this question, but here we go...

To prevent misunderstandings: this is *not* about the *ask ubuntu newsletter*, but the *Ubuntu Weekly Newsletter* (sent by Elizabeth K. Joseph).

----------


###Since long
I have been subscribed to the *Ubuntu Weekly Newsletter*. I never read it actually too well, until today. My eye fell on a subject in the mail:

***People Contributing the best questions and answers this week:***<br>
Since at least once or twice, one of my answers was generously voted on, I expected to find my name somewhere in older mails. I admit.. as vain as it gets. 

Digging through the mails however, I didn't see my name *ever*, which made me wonder, what is the algorithm behind the decision to mention questions or answer as "the best"?

###What it is not:
- The votes on the questions or answer
- The activity on the question
- Ask Ubuntu Top 5 Questions this week

Since these are mentioned separately.

Therefore, I asked the newsletter folks, who directed me to the [Ask Ubuntu script on Launchpad][1], which didn't help much. I was advised to ask it here, and so I do.

###EDIT
A thorough search shows I *was* on the list a number of times, but the reason why puzzles me even more. Weeks with relatively high rank (e.g. in the example from muru's answer, [#3][2], Feb 7, 2016 - Feb 13, 2016), I wasn't on the list, while I *was* on the list on e.g. 30-9-2015 ([#34][3])
