I don't have anything much to say that can be adequately "fixed" about the main page. It's just, on a fundamental level, not my cup of tea. I think it can be a bit overwhelming to new users who are overloaded with lots of information at once, and all of this information bleeds together. Everything sort of looks the same, and there's no visual differentiation between your toolbar, where you have the option to check your favorites, compose an entry, manage your diary, etc. and the entirely-too-long list of diary entry previews.
It looks like it's trying to be a little tumblr-esque, but without the features that allow for the site to be truly modular, like a real good search, tagging, etc. A page style like this might have its uses, but IMO not as Bloop's landing page. A page like this would be great if you're going through a hashtag, or to have as your favorites, with an easy way to fully read an entry and interact with it (comment/like/etc) right on the page, without navigating to the diary itself.
