The Gazette on Friday announced the fourth of its four new Friday Voice columnists, who will write about once a month each (rotating every week) on different issues:

• Laughologist Albert Nerenberg on the wacky side of climate change
• Arts freelancer (and Rover publisher) Marianne Ackerman profiling people and places in Montreal
• Gazette web editor Asmaa Malik on human interaction in the digital age
• Bookworm Heather O’Neill talking about a book that’s affected her life

In addition to these, local arboreal expert Bronwyn Chester, who had written a weekly feature called Tree Tuesday for the Spacing Montreal blog, now has a weekly column in The Gazette on Sundays called Island of Trees, and is leaving her unpaid Spacing column. She also has a blog devoted to the subject.
