I like the nice design of the site, it makes me feel good on the inside. I am sure it's the reason why Apple products can charge $50 for a power cord, because they have nice design.
With that in mind, your "Post Your Question" and "Post Your Answer" seem to be out of date when compared to the rest of the site. It does not change on hover, or on click. It also has a very Web 1.0-like look (the padding and padding height on top is less than on bottom).
It just does not look like the rest of the quality material on this site.
The reason why I bring this up is that I feel like attention to detail really makes a site stand out and I feel like you are selling yourself short by leaving such an item undone.
To the editors, the "Post Your Question" is no different than the "Answer Your Question". It just depends on your perspective of the question. Its also the same button as "Save Edits"
So as you can see I included the "Add Comment" button and the "Answer Your Question" (For you it's "Post Your Answer"). There is the spacing issue, measured in gimp.
