I was going to mention that Vim’s website[0] is possibly worse, but then I looked up Neovim’s website[1] which was definitely made with mobile in mind, and isn’t terrible.
I went to vim.org, I was never there, because I go to church.
I find Leo's website worse than vim's. The vim site has a clear green download button. This is a straightforward design feature I like.
The picture with the kid and the power tool is funny. I liked that too.
Then, a advertising banner on the right colum. Seriously? On the homepage of one of the most [will not bring myself to say a deserved positive adjective here, because I go to church] open source projects.
Edit: Church references church of Emacs of course.
