Re: Your redesign stinks, sorry, but it does
I have to agree with just about every criticism I've seen.
Failure of middle-click to throw to a new tab is absolutely indefensible. They had to deliberately disable it, whether that was the desired end or just an accidental by-product of some useless crap "modern" web design effect they wanted.
But, I have to say, middle-click is working for me (Exploder 11/Win 7 - not my usual choice but it's what I happen to have in front of me right now). Maybe they have already fixed this or maybe it's whatever browser you're using.
If it still isn't working for you, you could try control-left-click, which on some versions of some browsers is equivalent to a middle click.
