After the caning tech stocks have suffered this year, it’s understandable that few companies are looking to brave the public markets right now. An exception is apparently Instacart, which, according to The Wall Street Journal today, seems determined to go public soon come hell or high water. It may have a good reason—The Journal’s report said the shares sold in the planned IPO would be primarily those held by employees, as a way of providing them with liquidity.  Even so, you have to wonder whether Instacart shouldn’t come up with an alternative way of achieving that aim.
