Hi, thanks for the feedback! It's not my blog actually, we are a startup (hence the top bar for users), we will take the feedback on board, maybe we got a little excited with the size of the topbar :)
Worse than that: from my end on Chrome (beta) running in Ubuntu, the bars appear to stay in their original location when scrolling which makes them cover content and generally bug out. I could not read the article at all!
I think it's the combination of the top and bottom bar that make the site feel a little weird for me.
