I support giving journal owners whatever information is (a) useful, (b) non-invasive to others. (there's a (c) there of "feasible to collect & store", but that's for Rah et al to judge).

I disagree with having an "opt out of having my stats collected" option - if it's invasive enough that that's warranted, we shouldn't be collecting it. I'm not sure if that was actually part of the suggestion, or just part of the "what LJ does" explanation ☺️
