ST. PAUL—Wanna get rid of that snow? Your ability to hire someone to plow your driveway with a simple tap on a smartphone has expanded in the Twin Cities. The on-demand snow removal service SnoHub, a free app, officially launched here this past week. It joins Plowz, another app-based snow removal service. "We're very excited about coming to the Midwest," tech entrepreneur and SnoHub CEO James Albis said. "Minneapolis and St. Paul are an important market for us."
