Funny Video Sketches Website
https://www.youtube.com/user/ilariantsiteSeveral years ago, I created an original content website similar to http://www.collegehumor.com/ in my country along with three friends of mine. We did 50+ video sketches over a period of two years and we enjoyed unexpected success. We had a lot of traffic on our website, our YouTube channel has 13.5 million views, and our Facebook page still has like 40,000+ likes. For students creating content only in Romanian and for the Romanian people six years ago, these are incredible numbers. Doing that period, I also gained some technical skills like Adobe Premiere Pro, Photoshop, and Lightroom as we created/edited our own creations.
