I found the segment he did last night entertaining, and I can only hope that it continues. The crowd clearly dug the segment, so why not continue it? I think it has potential.
Turning Rose into essentially the Perez Hilton of WWE, being a gossip monger could be a great way of starting storylines, he could drop truth and that could lead to development and revelations in current storylines or begin new storylines, or he could drop lies and put even more heat on himself.
In addition to that, it could also be a very useful tool in adding fire to feuds in WWE, it also could be a way of WWE taking digs at itself (the line about Ziggler being with everyone, and also it basically just said 'yeah this whole storyline is over, lets forget it') or it could even be used to take shots at dirt sheets that post a bunch of stuff which isn't true.
If WWE let it, this could be a great addition to the show if used properly and give Adam Rose something to do and finally get him out of dark match/occasional Superstars appearance purgatory.
