what type of site is fmylife

I've noticed that many websites have types, like genres in literature. What type of site is fmylife and how much competition is in that niche. I have a site called ragingalcoholic[.]com and I may want to see if I can do something like fmylife with it. It is being visited but isn't producing any income. I'm thinking of re-purposing it.
Any suggestions

Thank you for your consideration
