Just to add......we wanted you guys to know that we aren't taking this thing lying down. As you may have noticed, the site has grown significantly faster the last 2-3 days (aside from today's downtime). This is the kind of thing we're working towards.
Again, we are working to make things better/faster/more reliable. No one takes this more seriously than us. And when the site it down, no one is more perturbed than us. So rest assured, we will make things better.
