It may seem a bit unusual, but I would like to see something along the lines of Artificial Jobs, as in a location where one can perform tasks and labour, repeatedly, to earn money. Sometimes when I log on and have no motivation to build, I would relish the ability to go somewhere and earn money doing something fairly basic.
Perhaps chunks designated for 'clearing', or farms you need to harvest and such.
This could also be used to create a set minimum wage for players interacting with each other in terms of labour - why should I clear Player X's land when I'll get more money than they're offering if I go to TheJobCentre? Essentially meaning richer people spend more, so that poorer people get more.
This is every likely a ridiculous idea, but I'm rather tired and there didn't seem to be anything else to contribute on the forums.

Second idea: Assign certain event staff for especially 'forums events', essentially keeping the forums lively, active, and entertaining. Twould be their duty to come up with thought-provoking thread, catchy games, and generally brighten the place up.
