I run a blog with over 5000+ followers, and post photos daily on there, roughly up to 50 a day. So helping you run/update your website with jokes/memes/ etc, would be an easy and also exciting job for me, as this is what I am passionate about.
Because of my following I know how to communicate with large audiences and keep a blog/website updated. I always work quickly and efficiently to complete the goal. which for me is posting daily to my blog, and also to your website, and facebook page.
I also have lots of experience with facebook pages as I used to run some a few years ago, I assume a lot has changed since then, but I know facebook very well, and I am very confident with the internet so I am sure that I will pick it up very quickly.
