As a dismembered head living eternally in an infernal jar, my Stack Overflow addiction would be easier to indulge if I didn't have to waste time moving these wretched mechanical hooks to push around a primitive mouse.
I could answer questions faster if Stack Overflow were linked directly to my dopamine-saturated brain.
Why are you limiting interactivity with post-human users? The site works great for blind users and even the superintelligent mongoose that occupies the space next to my jar.
And, more importantly, such an interface would be useful for normal users, too! In fact, if you designed such an interface it would probably scale to other web sites as well. You could win a prize in design or something. The ideal solution would work for non-human users as well, such as Asgard and Romulans.
