I'd like the URL to be valid (meaning base64 the compressed data) so that we can get the data to the kernel.org server as easily as possible. Making the app a requirement for reporting is too onerous for non-developers. I see no reason we can't link to (Open in/Install) it on the webform though. I see your app as a great tool for people developing the kernel or curious about what happened, but there will be a significant number of users who don't develop (possibly anything) who won't go to the effort to install an app just to help us out. Knowing how many of those folks are affected by the bug is, imho, a very important data point when triaging bugs. Even though these 'users' don't talk on lkml, they *do* exist. And they say mean things like "Linux crashes on my $LAPTOP, it sucks." I'd rather not have to get a facebook account to learn that. :) thx, Jason.
