I’d like to say that I think Mint is hugely over priced.
The range of statistics is very limited. No country, browser, OS. Only the basic visits and referrers.
Support is discouraged. You may not want to offer free support, which is fine, but it’s not a good idea to say answering questions makes you grumpy. For the price of the software I’d at least expect a decent amount of support though, whether it’s already answered on the website or not.
I hope Mint is a work in progress as I really like the UI. Google analytics has just as good UI, but has lots of other features. If Mint supported access logs I’m sure people would ditch Google for it.
