Co-founder Tim Copeland has announced the ascension of Brian Calhoun as the new CEO of open source firm Silverstripe, the mum-friendly CMS that was nominated "Most Promising" by Packt. (By week's end, they just might win it, too.) Brian Calhoun is a Silicon Valley cowboy with about 20 years of software experience notched to his belt. We look forward to seeing how his visions shape the company. Tim will be pursuing opportunities to expand SilverStripe under his own new title, that of Business Development Director. And he's throwing himself into the realm of exploration with gusto. Check out his interview with Dion Almear, who founded and currently works at Google. Earlier this month, SilverStripe released v2.1.0 of its primary offering, specially enhanced for comment modders and widget-wielders.
