I don't browse by date or tags either, so I don't care about them. Actually, I don't pay attention to the right section of the page at all, as the design suggests so. So if you want to put important stuff there, you better not.
Also, the tags seem quite.. vague, but that's none of my business as I don't read them, I just browse through Neatorama.
I don't use the social whatever buttons as I don't have an account in those, so this goes under "whatever" as well.
I'd rather read a version with more posts in the same page. Even though there already is plenty, I don't like pressing the "next page" button.
Perhaps you should create a separate version for iphones and like?
