Didn't think a forum update was ever coming. If it ever came I kinda always thought that a quick fix along with it would be that the forums width would increase to make use of that dead black space to the right. I toggled the ads back on just to see if all the space was actually being used, but no. Pretty sure my display is standard too so what's up with all that space? Checked the site on my mobile also and still theres clear excess space...
Anyway, I like the update, but the thumbs would be better if they were fractionally smaller maybe, and certainly if they were to the immediate left or right of the user's profile. Most of the time you'll see short posts, and you're often scrolling a little excessively and needlessly through a thread because the thumbs are both large and below the user profile.
My biggest peeve is opting for thumbs over arrows; the Facebook, Youtube generation see a thumb and it's a more of a like/dislike button; not upvote/downvote, and it seems that that's precisely the association you want to avoid.
Here's a quick example of the suggestions (I only changed the first post and moved the ad):
