I would say the only real downside I see here is that I only really see one article on the screen at a time, while I could see multiple headlines on the old one.
"I have to work on the article entry format."
As I mentioned up front, I am working on this. However, when all is said and done, it will not have the same cramped feeling as the current design. Readability will take priority over information per square inch.
The only comment that I have is that, like it or not, the majority of TBD viewers in the future will be using phones or tablets (and the desktop view will go the way of the dinosaur). Therefore, the page should be designed to accommodate phones and tablets.
Are you saying the mobile view is currently broken? I will be be making a mobile friendly header with a drop-down menu, but that is the next level of design. Currently, everything is mobile responsive and looks good on my iphone 6s+, although as mentioned - I am working on the article format/presentation.
