I've looked at many reporting tools, most of them are probably great for corporate/enterprise stuff.

I'm self-employed, so I have no boss or shareholders that need pretty reports with bar charts. In my case my site is deeply database driven and I can build engagement statistics directly from real data using complex SQL queries.

And while there's only a few such 'reports' that I check regularly, most of them are temporally incongruous—I think that's how you'd describe it—in that they look at what happened in the past contextualised by what's known in the present. (E.g. tracking engagements from new/irregular users, while they were new/irregular users, but which subsequently became regular users.)
