When I grep for "<contributor>" or "<revision>" in svwiki-20080310-pages-meta-history.xml I find 5,822,491 occurrences. But [[sv:Special:Statistics]] says there have been 6,246,812 edits. What are the 424,321 edits in between? Deleted pages?
According to [[sv:Special:Statistics]] there are 58,087 user accounts, but <contributor><username> has 28,416 distinct values. Is it realistic that half of all registered usernames have never contributed a single edit (to non-deleted pages)? Can we find out what happened to them? Did they write spam that was deleted and the username permanently blocked? Did they just register their name to stop others from doing so? Or did something go wrong during the registration?
Of those who did contribute something, of course most usernames only made very few contributions. This is a long tail. So how do we separate the regular/serious/active contributors from the occassional ones? In [[m:board elections]] to the WMF, a limit of 400 edits is used, and this threshold is as good as any.
In <contributor><username> of the sv.wp dump there are 900 names (and 104 addresses in <contributor><ip>) that have contributed 400 revisions or more (to non-deleted pages). Of these 900, some 80 have names containing "bot" and some are sock puppets, but I guess that 800 could be eligible to vote. There are 81 admins on sv.wp. Is one admin per ten eligible voter volunteers a "normal" quotient? It also means we have one eligible voter per 12,500 speakers of the Swedish language (800 out of 10 million).
I think 800 is the number of volunteers that should be mentioned rather than the 58,087 mostly inactive usernames.
