One of the tenets of usability is availability.
When your product is not available to your users, well, and not to put too fine a point on it, your product/service has a usability issue.
I have been using All the Web a lot more of late. Mostly because it works when I want it to work. Can’t say the same of Google.
I feel bad complaining about a free service. But that free service is so much a part of the culture of at least the US that google has become a verb. You never hear anyone say, “I’ll webcrawler it.”
At potentially more than 100$US per share, I am not sure what the value proposition is for Google. Perhaps all the hiccups of late are the ether’s way of telling Google to be accessible in more ways than one.
