You should combine both a community for new visitors register to your site and posting funny stuffs.

I saw more funny websites are growing and having big traffic, why not try to jump into this niche if you can? it is a good way to start.

In the past, I had a funny story site which has more funny stories, jokes,...but I could not manage it when it has huge traffic, some ddos attacks and site was down...I didn't have experience to keep it live.

The advice to grow with type of this site you need to use social networks, forums and blog and promote your sites there. It will drive more visitors to your site and you will get new users and comments.

An important thing you will not want to miss, that is SEO, more people are searching for funny sites, if you can do this right way, an amount of huge traffic is coming to your site. Good luck!
