Last Summer I was contacted by 4ormat (an online portfolio hosting service I have been using since forever) because they wanted to feature me in their Spotlight section! It was very unexpected, yet very flattering to be considered noteworthy on a site that features so many talented artists, so naturally I was very excited by their request.
I also happen to love their service, so I have absolutely no problem being used as selling point. They truly make my life easier!
