Now, this is probably a completely rational move from the company's perspective. Silicon Valley over the last few years has been backstopped by acquihires and other such soft landings, and big companies desperate to hire outstanding talent are often very willing to pay high prices for a great team. From the landing page at least, it certainly doesn't look like the Just Landed guys are amateurs. They're probably a very talented, capable team.
If they're successful, I won't begrudge them their success. However, I do lament the idea that the best minds of a generation are being focused on getting people to click on ads and minimizing the number of loop-arounds you have to do at the airport. I don't buy the idea that these guys wouldn't be focused on "harder" problems if consumer web didn't exist; of course they would. This kind of talent rises to the challenge. The idea that these are the problems whose solution drives us forwards is just a monumental lapse of creativity. Technology is an amazing thing, and we can do so much with it. I really think it's just an exposure issue -- people are used to web, and fields like the life sciences or hardware seem mysterious and complex. How do those become opened up?
