Idea: Personal notes about a game/publisher/developer

[ALERTua]

While Steam Curator messages are important for me, I want to be able to also leave my own notes for myself on a game, developer, or publisher's page so that I don't forget certain facts about them.
This is very important for me to not forget that, for example, Gunzilla games are forbidden to buy, Todd Howard always lies, and Tynan Sylvester is a waifu.
Thank you for your work!
