Blether , a web application that allows us to create private channels to talk on Twitter without needing to follow the user or for them to follow us.
A simple application that makes it easy to follow and be followed so we can talk without anyone knowing what we're saying on Twitter . We just need to go to the Blether page and authenticate our Twitter account. After this, the Blether panel will appear where we must write the Twitter usernames of the people who will participate in the private channel.
Another way to do this is by directly posting a new status to our timeline with “ !b ” to start the application followed by the usernames of the people participating and the room name, for example: !b @gielfull @user2
