Last month, while trying to gauge the prevalence of different languages in the OGF community, I looked into the user signup data and made a chart of the language preferences specified during the account creation process. This chart represents around 380 out of 3350 accounts (those with under 30 edits were excluded). It's not a perfect snapshot of the community — many people specified multiple languages, for instance, so they are counted multiple times — but I think it's still pretty interesting. A chart including all 3350 accounts is here, but bear in mind most of those accounts never even made any edits.
