Github’s new-issue UI supports URL query param auto-filling of name, content and labels (as `title`, `body` and multiple `labels[]` parameters):

https://github.com/barnabywalters/weave/issues/new
?title=Name Of Issue
&body=Blah blah blah problems
&labels[]=bug
&labels[]=enhancement

URLs don't just give addressability, they give accountability. When there's a URL, someone is responsible for it. When a thing (concept, object, document, proposal, idea, etc.) has a URL, it can be discussed, supported, contested, referenced and documented.

URLs are valuable things. We must treat them with respect.
