Influenciada por discussões no Mastodon, tenho me interessado bastante sobre protocolos de mensageiros instantâneos como o #XMPP e tenho guardado nos meus arquivos os links de artigos sobre o assunto que tenho lido.

Decidi compartilhar aqui a lista de artigos encontrados com outros interessados. A ideia é ir acrescentando novos links conforme mais leituras forem feitas.

Os artigos estão em inglês, salvo se sinalizados com 🇧🇷 ou 🇫🇷.
