Open Source, Open Data, Open Standards

Open standards

Standards are #BAD

Existing standards never fit your needs

They are always outdated

They are academic and over complicated

Standards - the good part

Communication

Replaceability, Substitutability

Sharing

Interoperability

Standards are evil, but we ain’t got nothing better.
