Tag in Evernote

You can store many thousands of notes in Evernote. The problem is not to store the notes but to search them.

Tags can really help you to navigate through your thousands of notes.

Tags, in the Evernote context, are text labels superimposed to the notes. You can search the notes using a single tag, regardless of the note content. You can use multiple tag combined with booleans operators.You can also mix tags and text in your researches.

Then tags are elements to elements to bring order into chaos.

Tag in social networks

Tag in Facebook.

When you tag a person in Facebook the system sends a notice regarding his presence in a image.

The tagged subject receives an advice and has the option to eliminate the tag itself.

The subject's friends receive, if tag is allowed, a notification in order to visit and, eventually, to like and comment the image.

Then the tag finality in Facebook is to expand the posts visibility.

See the first image for an example of tags in Facebook

Tag in Instagram.

When you tag a person in Instagram the system sends to that person a notification.

The tagging finality in Instagram is similar to what happens in Facebook: extend the visibility of posts published on the network.
