Is it worth the time to keep this website?

My LG spent a year of after work time and made this website: www.tvfool.com. This web site earned some money from google adsense ($10-$20/day).
He is a completely tech guy and does not have time to think about how to make it a more profitable business. Since every day he just dives into his room after coming back from work, AS his wife I become very busy on providing him a better working environment including cooking, taking care kids, etc. (sounds like a complaining). I sometime think it may not be worth it to put so much on to it, but he thinks it is a good web site(some disageement). We truely appreciate your input! Thanks
