Create notes with geographic coordinates of current location to keep records of visiting places and linking them to map.
When you travel it would be possible to let your friends and family to see visiting places on a map altogether with other interesting information from notes you associated with those places, as well as comment your notes and add there own notes, editing the same document together and sync it with cloud storage. All required for that is to make that document available in cloud storage for your friends and family. For example, you can do it by creating new cloud storage account and share the account credentials with them. Or even share your geographic track, as described here.
To add a note with current geographic coordinate activate notes edit mode first (with "Pen" button), then select a list where new note should go and activate context menu simultaneously by long click on some note from that list or by long click on empty list. Select option "Add current geo location" from opened context menu.
