>I created a sort-of wiki page of her in my personal notes app. But then I went to the actual page and found the same information there

Usually when I read wiki written by more than one man and need something more complex than "born xxxx, died xxxx", I feel like the page was written by schizophrenic with OCD i.e. the information is not consistent and writer is obsessed by formal correctness at the expense of clarity. Thus I cannot understand shit unless I'm already well familiar with the topic - but then what's the reason for me to read this article?

I do similar things (and have came upon similar notes elsewhere) but my personal notes are still valuable because a) they are structured how I think, and b) I remember it better/it finds its way into my consciousness better by writing it.
