Why not make that board by the bounty hunter useful?
Have it where people can post fireteams so players can meet up and do things together instead of having to use 3rd party sites or randomly inviting other people in the tower who may or may not give a crap.
That way you can post a message on what you are planning to do and what or who you are looking for. Maybe your team needs a defender titan, or maybe you and a friend really need help finishing a nightfall, this would be a great way to enhance the co-op experience. Much better than randomly bringing people together with matchmaking. Could even go as far as offering rewards for helping other players out.
A question for the community. Would you use something like this?

Only problem with this is you can only have like 15 people in tower and there's no way 5 of them are gonna want to do a raid when you do. You would have to keep rejoining the tower over and over. Better idea is just a region chat in tower with different categories. Stick a spam bot in there and you're done.
