The recently launched r/Arabs Dialect Project uses Reddit to map Arabic dialects from the Middle East and North Africa. Many dialects are mutually unintelligible and have as much in common as Portuguese and French. Participants in the project retell a story from the folk tales of Nasreddin Juha in their native accent.
According to The Economist, the project intentionally stresses the differences in each accent, almost as if "an old uncle" were telling it. More than 25 samples from two continents have been uploaded so far. Since launching as a Digg-style link-sharing site, Reddit has grown into a massive community.
