Usability is not everything. If usability engineers designed a nightclub, it would be clean, quiet, brightly lit, with lots of places to sit down, plenty of bartenders, menus written in 18-point sans-serif, and easy-to-find bathrooms. But nobody would be there. They would all be down the street at Coyote Ugly pouring beer on each other.

Good software, like wine, takes time.

If something seems possible, that's probably because someone is already doing it. When something seems that it can't possibly work, nobody tries it. Real innovation happens when someone tries anyway, overlooking an obvious flaw, and finds a way to make an idea work.

Every day that we spent not improving our products was a wasted day.
