The Line welcomes another versatile, widely experienced Twin Cities journalist to its news staff with this issue.  If you read us regularly, you've enjoyed Elizabeth Millard's features (including her portrait of social media maven Garrio Harrison, her survey of urban chicken-raisers, and this week's look at local rooftop farms and gardens). But she is also a seasoned business reporter who has contributed to most of the enterprise-oriented magazines in town, and we're delighted to have her as our new Innovation and Jobs editor.
