I have checked around the site and I don't believe this is something that has been implemented yet (please correct me if I'm wrong) but it might be a cool idea to have blog posting on itch.
Developers could write articles on various topics of games development including on design, art, production, audio etc. I think this could be a valuable thing to have say for example if one developer had a game with procedural generation and wanted to write about how they did it but in a larger context, not specific to their game and then others with an interest in the topic could then learn from this. It just means people can share ideas in this way as part of a library of topics on game development instead of having to go through a game and to a devlog to learn about something. It can also allow people to write on subjects to do with other games not their own.
It could be a great integration into the site as this is a hotbed for great developers and ideas and could be like something akin to gamasutra.
Is this a good idea? Let me know what you think.
