Hi,
There is a phenomenon in Wikipedias in smaller languages: There activity level of people who actually know the language of the wiki and make meaningful text contributions is relatively low, and the activity of people from other wikis who make various technical edits that don't require the knowledge of the language is relatively high.
I call the latter group "helpful strangers". They can do things such as fixing categories, fixing invalid wiki syntax, editing templates, adding images, etc.—things that don't require knowing the language well, and can be achieved by copying and pasting, by guessing things from interlanguage links, or by writing language-neutral things, such as numbers or filenames.
Now, I've written "relatively low" and "relatively high", but these are just my anecdotal impressions. Has anyone thought of a way to quantify this more precisely?
