What Tom means is that, on the homepage the "Posts" and "Feeds" are
showing full/complete content of each post.
At this moment, there is no problem, because the 4 posts have almost the
same length of contents and each of them is not too long. But, just a
few days ago (when Tom was posting) the was the 4th post which has very
long content, while the rest 3 is very short, that makes a lot of spaces
on the left side.
When displaying the feed contents it is necessary to truncate its
contents, so that the really long feeds do not break our webpage. (This
is an easy-hack, just some lines of codes will do this.)
