Please do not use notes for general discussion or storing information not otherwise used in OpenStreetMap. For example never create notes such as "I was here on Saturday" or "There was a crime at this location". 
Don't use notes for yourself in a way which is useless to others. Although you can use notes as a reminder to yourself, you are also inviting others to look at it. Descriptions must make sense to other people.
