<https://launchpad.net/bugs/bugtrackers/+newbugtracker> requires a "Summary" of the bug tracker: "A brief introduction or overview of this bug tracker instance."
Out of the 95 bug trackers registered at the time of writing, 91 of them have a Summary that talks only about which projects use the tracker, what kind of tracker it is, and/or (occasionally) what its URL is. And Launchpad already has more structured database fields for knowing all of those things.
(The four exceptions are <https://bugs.launchpad.net/bugs/bugtrackers/freedesktop-bugs>, which says "french keyboards are always complicated"; <https://launchpad.net/bugs/bugtrackers/linux-kernel-bugs>, which says that it's not for bugs about distribution kernels; <https://launchpad.net/bugs/bugtrackers/mozdev-bugs>, which says that it's not for bugs about Firefox or Thunderbird; and <https://launchpad.net/bugs/bugtrackers/libburn-bugs>, which says "The trac bug tracker doesn't just do bug triaging". I don't think any of these are informative enough to justify the field.)
The redundancy of the Summary field is hinted at in <https://launchpad.net/bugs/bugtrackers/kerneltools-bugs>, where both "Summary" and "Contact details" have been filled in with "Blah blah blah blah Stupid LP boxes".
I propose that the Summary field be deleted. Instead, the page for a bug tracker should more prominently list which projects are registered in Launchpad as using the tracker, what kind of tracker it is, and what its URL is.

+1 on it, OT but I am the one who made that libburn-bugs one, there was somebody on #launchpad telling me to give some information about the bug tracker. Didn't know what else to write. As you said if I had written the URL's it wouldn't have achieved anything.
