I've been using Mint.com since 2008, and just the other day I contemplated how astonishingly little it has changed since then. The "Investments" section is still as unusable as it was back then (personalcapital.com is running laps around it). I think the homepage/log in screen was redesigned, and as you said, more overt advertising was added. Maybe there were some backend changes, but as a customer, the lack of progress is staggering.
