I think consistent metrics are good BTW, if that means all periods use same methodology, are revised when errors in input or scripts surfaced, are recalculated (if possible) when incremental insights lead to revised definition (so that older metrics remain relevant and comparable with recent data), and so on. So consistent metrics yes, but static metrics no. And that difference is relevant here. It seems to me I read not often enough about an updated metric in the world at large. Something like "inflation in 2001 in US has been reassessed to have been 2.2% where up till yesterday we thought it had been 2.1%" Erik -----Original Message----- From: Erik Zachte [mailto:ezachte@wikimedia.org] Sent: Friday, May 22, 2015 23:15 To: 'A mailing list for the Analytics Team at WMF and everybody who has an interest in Wikipedia and analytics.'

Hmm, the article's main story is about how historical in-wiki data are unreliable and a periodic recount is needed. Just saying. And the main theme in comments is "do we care about article count?"
