On large monitors it appears at the top. That's because I restricted the width of a post's content on large monitors, in order to prevent a post's text from stretching too far to the right and left and becoming annoying to read. This created a fair amount of white space on the left side of the post which seemed like a natural place for the Rec button. Given that most OPs on DU are not super-long, and also given that this would only affect people on larger monitors, which meant that they would have less scrolling to do anyway, I thought this placement wouldn't be a problem.
I should also note that your preference for where the Rec button is may depend on whether you're a recommender, or a reader. If you're someone who likes to recommend threads, I understand that it's a bit of a pain to have to scroll back up a long OP to rec something. That's not ideal. However, if you're a reader -- either a member who doesn't rec much, or a non-member who doesn't have the ability to rec -- I'd argue that placing the rec information at the top is more useful. It's helpful to see how many recs a thread has before you read it.
The ideal solution for larger monitors would be to leave the Rec where it is but have a second Rec button at the bottom of the post. We tried to do it this way very early in development but unfortunately we ran into unexpected technical difficulties which prevented us from getting it working. It's something we could perhaps revisit.
Bottom line... when it comes to fixable vs. non-fixable, this is one of those issues that does allow for some flexibility -- the Rec button could be moved. (Or potentially, an Account Settings option could be created to allow you to move it as an option, although that would be a fair bit more work). I'm just not 100% sure it's necessary at this point...
