Contrarian view: I hate issue templates (at least as implemented) because they utterly cripple search for any word that appears in the template (and I’ve had this bite me more than once or twice). Most of the stuff people use templates for should instead be instructions outside the box, but GitHub doesn’t support that. If you’re going to follow the “big blob of text” model rather than having separate fields for much of the metadata, then your goal should be to have as little text as possible in any template, and avoid any words that people might want to search on.
