With break getting over some people may be coming back with new systems, new games, or getting their system online for the first time and are looking for someone to join them in playing the game. This is your opportunity to find other people on the wing that play the same game as you and talk to them about it. It also allows you to join them online for game play. Even if you do not want to provide your username it allows you to see what other people are playing and ask for their opinion. I got you stated by putting my username for both Xbox 1 and Steam.
