For someone who loves Draw like I do, this is very nice. All the shapes you draw are now smoother in 3.1 with anti-aliasing.
I know that the reduction in the blogging software will throw this off a bit, but I think it'll be helpful. Here's the basic drawing.
Now, keep in mind that if you're exporting to Photoshop, Gimp, or other raster programs, that you still need to be careful. The left shows the same drawing exported as PNG, the right a JPG. So far so good, or at least not terrible.
Here's what they look like at 400% magnification in Photoshop. PNG (first) and JPG (second) both look kind of icky.
If you are exporting a Draw drawing, your best best is to EPS, or even PDF.
Here's an EPS drawing exported to Photoshop, rasterized, then magnified to 400% like the others.
And here's an exported PDF which is openable in Photoshop as a raster file. For my money, it looks better than the EPS, at least at that magnification. It doesn't matter much if you're just using it at the size it came in at for the EPS. I do all my book covers in Draw, then export to Photoshop to rasterize and turn into JPGs for the printer.
