On the eve of #OpenStreetMap's 20th anniversary, it is slightly upsetting to see the pivotal piece of software that stopped OSM from vanishing in to obscurity and that was, between 2006 and 2014, the 1st contact with editing OSM for most contributors, considered not-notable by @wikipedia

@simon @wikipedia @richlv @seav @edward Another example of the arbitrariness of Wikipedia.
I'd think TBL spending a minute or two in a TED talk in 2010 demonstrating editing with Potlatch, might suggest it had a huge cultural impact.
