Just put the image over our username.
The float:right or whatever is squishing the paragraphs too much on my mobile in Firefox and Chrome.
Besides, if the username is that long, maybe that is itself the picture.
The post text will now wrap around the comment-icon image on the right which means the post content will stretch to 'fullwidth' beneath the image.
Along with that we've also done a few margins and sizes tweaks to make better usage of the horizontal space for Forum posts, this then means you'll be able to see more of a Forum post content in a viewport (specially in the case of mobile) than you used to.
