"The fragility of free is a catchy term that describes what happens when the free money runs out. Or — perhaps more accurately — when the investors/founders/venture capitalists run out of cash, or patience, or both. Because at some point Twitter and all other companies have to make the move from ‘charity’ to ‘business’ — or, put another way, they have to make the move from spending tons of money to making slightly more money than they spend.

It’s at this moment that we begin to see the fragilities of the free system. Things that never had ads, get ads — things that were free, now cost a monthly fee. We have all seen it before with hundreds of services — many of which are no longer around.

As with great works of art, you must look into the past to appreciate the future. With roots as far back as the 1970′s, the humble icon has come a long way. Following is a collection of icons though history. Although there have been many other operating systems in the time between 1981 – 2010, I’ve hand picked the ones of the most significance to modern icon design.

Last summer, the world’s top software-security experts were panicked by the discovery of a drone-like computer virus, radically different from and far more sophisticated than any they’d seen. The race was on to figure out its payload, its purpose, and who was behind it. As the world now knows, the Stuxnet worm appears to have attacked Iran’s nuclear program. And, as Michael Joseph Gross reports, while its source remains something of a mystery, Stuxnet is the new face of 21st-century warfare: invisible, anonymous, and devastating.

When you hear people sound alarms about the future of news, they often gravitate to two key endangered species: war reporters and investigative journalists. Will the bloggers get out of their pajamas and head up the Baghdad bureau? Will they do the kind of relentless shoe-leather detective work that made Woodward and Bernstein household names? These are genuinely important questions, and I think we have good reason to be optimistic about their answers. But you can’t see the reasons for that optimism by looking at the current state of investigative journalism in the blogosphere, because the new ecosystem of investigative journalism is in its infancy. There are dozens of interesting projects being spearheaded by very smart people, some of them nonprofits, some for-profit. But they are seedlings.
