I saw a combination of Twitter and Facebook, in a way. But I don't mind at all, because it's very sleek! Really hard to choose between the old design and new design! They two have different feels.
After testing for a bit, the only question I have for now is, must we use Source Sans Pro font? Source Sans Pro font looks good only in certain font sizes. So, I personally prefer to stick with Whitney for the entire site. Looks neater in my personal opinion. =)
Hope to see dark mode in the near future too! ;-)
