Today's Cool Site of the Day is perhaps the biggest challenger to Facebook that we've ever seen. The site is called #Ello and it's so cool (so 'no ads' focused) that you need to be invited. Request an invite. Add this page to your ‘social media’ related bookmarks. And see and vote for today’s site here (on the day of this post) and give it a ‘thumbs up’ above…and, of course, SHARE THIS POST (links below)!
