For the first time ever, my personal blog has a light style. It feels fresh, actual and very different from what I'm used to. I like it!
I grew tired of darker styles because they rarely age well and have to be replaced over and over. Dark styles, when not done properly, will easily make your website feel like a dark and lonely, obscure corner of Internet. You definitely don't want that.
I also decided to move from Open Sans to Lato for a more formal feel, I think it does the job pretty well!
