Curate, connect, and discover
It sucks for some big media thing to incidentally have an idea you also had, but never posted anywhere.
Because now if you do anything with it people will go "omg this is like [blank] ! I can see you were inspired by it !"
And I'll say "no actually" and they'll be like whatever, but in the back of their mind they'll think I'm lying.
I guess the positive thing is that the whole time I thought maybe it was stupid, but actually it seems like everyone liked it and thought it was cool. In a way you made something people clearly enjoyed.
