Forum Discussion

Forum users are weighing in on the idea of storing data in favicons. One user said:

Oh, I am so aligned with this mentality:

   A monitor is storage.
   A keyboard is storage.
   

Forum posts are storage. Markov-approved tweaks in an edit, over time, certainly enough for quite a lot of storage.

Another user pointed out that

PNG has comment chunks tEXt, zTXt, and iTXt. You can have a completely normal image whose file is stuffed with as much content as you want.
