From the Puerta del Sol blog:
There’s an increasing number of “pedias” on the Web, and now we have Madripedia, which aims to become the biggest ever Madrid-based encyclopaedia (in what’s probably a limited field). It follows Cordobapedia, which has done the same thing for Córdoba since 2005, and which now has 3,700 entries (Madripedia only has 850+ so far). So it’s over to you! Any experts in cocido madrileño out there?
