Change the name!
I love your site/service! And I donate whenever I can! And I recommend it to everyone! But living in a prudish country (USA), the name can be a turn off in some circles. For example, I've told a group of people about it, then had to pull one person aside to tell them the URL quietly. (Of course, maybe *I'm* the prude.) And most people don't know what 'raster' means. Anyway, this change would be easier than all the tough software fixes the other suggestions require, and I guarantee it will increase usage. You could have a contest! My entry would be 'blowitup.net' -- o wait, that would get the wrong attention too. Maybe just f*** the USA, huh?
