There's a few major factors that decide whether site staff is fit for running a site. Obviously people need to be prepared to put aside time to work on the site. They also need to have the right skillset; if you're running a website, you'll need people who know how to handle the website code and such. Last but not least the staff needs to be able to work together as a team.

This last point is why it's a very bad idea to appoint a new staff member by popular vote. A reason why Jazz2Online staff was, until a while ago, composed of a lot of DM members was that they knew each other and thus worked together well. It's not some evil plot to gain as much power for the clan; it might as well be a simple side effect of forging a team of people who work well together.

Considering what Vegito and Grytolle said, I bet that if someone with good web coding skills who is willing to spend time on improving JJ.net and can work together with the current staff shows up, he'll be taken in regardless of clan allegiance.
