Doubt he's the only one who can see it. It's written up in many stories and most people using Twitter can see how much of a graveyard it can become at times. (It's the social network I use most, so I'd rather that weren't the case.)

This could be purely a move about PR and legacy. In recent times we've seen Yahoo and then Microsoft make expensive moves in an attempt to gain relevance.

I'm not sure it'd be the rank and file employees who hold Twitter back, but anyone steering it?
