It's hard to run a site like that year after year for longer than a few years when you have competing priorities in life (kids, partner, job, etc). Especially when it doesn't make enough money to justify giving it more focus.
In the case where more or less one individual is driving so much of the content, the project is particularly susceptible to dropping off the face of the Earth. Spread the involvement to multiple people and then you're working by committee plus splitting the proceeds.
If there weren't a number of people here starting topics and carrying on by themselves, Hoops would be a lot more susceptible too rather than being entirely reliant on my personal interest in basketball.
