I use Feedly to follow around 100 different digital marketing and social media websites. Makes it easy to look over all the headlines, gain a lot just from those, and then click into the ones I want to read, all in one place without the need to go to every single site. I generally take 30 minutes to do it a couple times a week. Share the best on social media and have built a following of more than 100k from doing so on Twitter.
