I was a Web Developer during the first dot-com boom, and now that I work as an iOS engineer during this boom, I'm shocked at how many of the same mistakes are being repeated.

On almost a daily basis I get recruiters contacting me with interview offers from companies who have no chance of surviving past the end of the year. Their messages are often accompanied with bravado about their company's VC backers' other, more successful projects, which only makes me more skeptical.
