If you don't have active and dedicated regulars on a Server, nothing will be achieved. Nothing.
Hub won't change that
More Servers won't change that
Consistent threads from Members or Players regarding this won't change that
Like DrLee mentioned:
Ingenuity. Creativity. Patience. Dedication. Four requirements of a happy Server that I am sorry to say are lacking in most of our playerbase. Concentrate on one thing, and work at it.
Server too boring? Start getting more enthusiastic and spontaneous. Do things that are out of the "norm". Who cares if you end up dying more, it makes it a much more enjoyable experience for players to see someone having a good time who emanates a sense of "fun".
Repetitive Wardens? Do something about it by calling Warden. Have some fun, do things that may end up with your CTs demise (I know, it isn't your job to get them killed). Doing so will get the T side more actively involved and they'll be more likely to have more fun. Don't do votes to see what they want to do as that kills the creativity.
Too quiet? Not enough action going on? Liven things up. Mock the Warden, mention some fun things to do, make our players feel welcome to the Server by actively talking or saying things like "This guy (random player) is my best friend now, and if he dies, so help me god I'll avenge him". Chances are that player will feel more welcomed to the Server.
Little to no people on the Servers? If you aren't busy and have nothing planned early the next day, why not grab a couple friends and mess around on Jailbreak or RPG surf, or have at you. Dedicate 1-2 hours of your time every day at a certain time frame (Morning, Afternoon, Evening). This is called dedication. There are times where if you have the right attitude and are enthusiastic, you can have the Server grow from just two people to 14 in the middle of the night. (I have done this many times, it takes effort and patience.)
All in all, the only way to make a difference is to do it yourself. Don't wait on others to do it for you. If you want to make improvements to the Server, you can do it by changing your outlook on everything and doing something. This applies to anyone in general, not anyone specifically.
