Instead of having to remember the whole
apt.ubuntu.com/p/package shebang, it would be easier to just support
apt.ubuntu.com currently doesn't have the nicest UI in the world, but https://wiki.ubuntu.com/AptUrlRedirector suggests more how it should work. I hope I'll get some time to actually implement nicer screens on apt.ubuntu.com to make it more worthwhile to link to.
It is my understanding that apt:// protocol links are deprecated. These provide a terrible experience on non-Ubuntu platforms, with no further explanation of what Ubuntu is and how they can get the software they just clicked the aforementioned link for.
Granted, apt.ubuntu.com currently suffers this problem as well, but it is my hope that its authors will use the free advertising space it provides to start a conversation with non-Ubuntu users.
