I work near the people that did goo.gl, and even though it has higher uptime and lower latency than any other url shortener, there's pressure on them to make it even faster and more reliable. We definitely have an institutional mentality that speed and reliability are the best features, and every other feature is secondary. (Not saying this is a bad thing, it just biases us towards certain types of products.)
For most "panda" tasks, isn't that the case? When people use a product to do something, they evaluate it based on how well it helps them accomplish that. Speed and reliability are important features there.
This model completely falls down for "lobster" tasks, which may be why Google sucks at social. But a URL-shortener, along with most of Google's products, is a panda task. I don't think that the emphasis on speed & reliability is misplaced there.
Agreed. I wouldn't say Gmail is fluff, either. Of course, he's equating fluffiness with non-profitability, but I think that's wrong. I doubt he'd be willing to stand up in front of a roomful of geeks at a conference and call Twitter fluff.
