[Foundation-l] Banners to increase editors

[Nicholas Moreau]

Along Keegan's idea about encouraging contributions in the reader's
native language, does Wikimedia track the preset language of visitors?
I know some analytics packages do, not sure if this is against
Wikimedia's privacy policies.

If the server senses the reader is preset to en, and looking at en,
then no message would be displayed during the campaign. If their
preset is say, sl, and they're looking at en, or vice-versa, then the
message would appear.

Is this technically possible? Is this within the boundaries of taste
(ie not being creepy)?
