I'm not sure what this is such a hard question. Here's how I see it: A) Making decent $$, -Hire an editor to maintain site -Sell it for decent profit -Focus more time on it and less on others B) Not so great $$, -Abandon -Attempt to sell -Don't invest any more time/effort/$ IMO
Hire someone to manage them. you can pay them on monthly basis. Also you can earn from advertisements.
