Thank you for discontinuing support for IE6. As a web development firm, we would love to stop supporting IE products. being relative pussies, however, we do not draw the line in the sand. i would absolutely love 37 Signals if they would just say no to IE alltogether. No more non-standards-based support. I think that once a firm with the reputation of 37 Signals wold leave the MS browser behind, others would follow suit and the market share of this craptastic browser would plummet like a rock in favor of other, better browsers.

That would be instant death for any business related web product, most businesses are Microsoft-centric no?
