"Listen, not a year goes by, not a year, that I don't hear about some escalator accident involving some [explicative deleted] kid which could have easily been avoided had some parent - I don't care which one - but some parent conditioned him to fear and respect that escalator."

The above quote comes from my favorite of the Kevin Smith oeuvre, Mallrats, which stars a pre-My Name is Earl Jason Lee. Released in 1995, writer/director Smith had no way of knowing that a new threat to escalator safety was looming in the distant future ... the ubiquitous Crocs (NASDAQ: CROX) shoes.

I'm not a mother, myself, but evidently these brightly colored clog-esque creations can be a parent's worst nightmare (I am an attorney's wife, so can I call them a lawsuit waiting to happen?). The shoes, while mystifyingly fashionable and in high demand, can cause playground accidents and lead to uncomfortable kids, when the holed footwear becomes full of playground detritus.

I'm attending the 2006 Blogher Conference in San Jose, California, and many of the net femarati are here. I just finished listening to an enlightening talk by the co-founder of Blogger (now owned by Google), Meg Hourihan, and the co-founder of flickr (now owned by Yahoo!), Caterina Fake. Moderator Marnie Webb pointed out that both of the products for which the two speakers are famous, were accidental by-products of their respective companies' original mission.

Fake was working with her co-founders on a role-playing game, while Hourihan was working on project management software. Declaring the concept of a stealth period "dead," the flickr co-founder mentioned that user feedback was central in determining how the photo sharing software would be shaped; and Hourihan echoed that sentiment with regards to the very useful blogging software her company, Pyra, developed just for fun. "If we had started out to create a photo sharing site, it never would have happened," said Fake. "We would have done market research, and discovered that all the money was in on-demand printing, and that took too much capital investment, and we'd never make money. We would have decided it wasn't worth it."

It's quite an interesting detail of product history and it's amazing to think how many great, world-changing products were accidental. What's more, it's worth considering from a management strategy point of view: how does a company encourage its employees to invest time in offshoots of the central strategy, and then fail to analyze those happy accidents to death? Are big companies forever destined to buy these providential mistakes simply because they never would have made sense, had they been "product developed"? Even Google, king of the entrepreneurial, "throw it up against the wall and see what sticks" spirit, had to buy Blogger. Which companies are best positioned to find and care for accidental successes?
