Why the condescension? The user's name is clickable and his profile shows he hasn't used the site since March. Instead of being rude, perhaps consider why his experience wasn't sticky.
To me, this behavior solidifies further Google's transition into the Microsoft of the 90's role. I guess that puts them at 2020 for being virtually completely removed from innovation and fully in the role of a differentiation defeater.
Microsoft could turn around and so could Google, but it's very hard when they're so established that short-term risk to profits becomes a major concern.
New Mogul was the first I've seen of this and was the best. I think New Mogul's success was also partly due to the intensity of the financial crisis and people's interest in understanding how it all works. Nickb vanished, unfortunately, and New Mogul eventually fell.
No site has been able to replicate the New Mogul community and I don't believe it's the UI's fault entirely, though New Mogul actually did a good job sprucing up the default look. I believe the intense interest along with communal enthusiasm just doesn't exist in that industry under normal circumstances. And certainly not enough for a shared information / aggregation system to prosper.
Consider the nature of the industry. Knowledge is power. If you're not all in a sinking ship together, why would you give up your competitive edge?
Think about it. You walk into a video store, you see 8-Minute Abs sittin' there, there's 7-Minute Abs right beside it. Which one are you gonna pick, man?
