O Philatelista is a philatelic blog in Portuguese that was aired in May 2013 and celebrated its 10th anniversary this month. What is exceptional about it is its consistency: 3636 posts from 1 June 2013 to 30 April 2023, i.e. in 3621 days. This is EXACTLY one post per day over the 10-year blog’s lifetime!
Mario Paiva is the tireless figure behind the blog. His readers are informed about new stamp issues, newly published catalogues, general literature, exhibitions, auctions and other philatelic events, with emphasis on the ones of Portuguese or Brazilian philatelic interest. He often participates in philatelic exhibitions all over the globe and proudly presents the blog’s awards online. Mario is also present on both Twitter and Facebook.
