I had an opportunity to meet Marin during high school, where he was has excelling both as student and as a programmer, achieving great results on algorithmic competitions.
I also had an opportunity to track his progress through university, where he continued being a top student and competitor.
Besides being a brilliant engineer/programmer, he is also not shy to "hustle" and get his hands dirty when needed, quite the opposite.
Marin was always showing entrepreneurial spirit, working on interesting side projects, and having seen first hand some of his efforts with QuickNews, I believe he is approaching it in the right way, methodically and passionately. It is obvious he knows a lot about startups and every time we chat, I learn something new! I myself got hooked up on QuickNews and am now using them as my main source of daily news.
