Being a content curator is all about displaying information. We don't create the content, we display it. We share it - and people read it. But, first you have to display it. There are several skills involved in displaying content.
Approach friends, co-workers, content creators, and others with your Scoop.it feed. Would another blog/website find value in your content and Scoop.it feed and agree to put the code up somewhere on their site? How about content sharing or trade?
If someone is warm to the idea but wavering, offer them a trade. Barter with something they would like — for instance you could give them the featured spot in your Scoop.it feed for a week, a month, etc.
When you share a Scoop.it post do you just share with Twitter, Facebook, LinkedIn, or the other popular social media sites? While potentially valuable due to their market size, these sites are plastered with sharing, wall to wall.
Look at other sources where you might actually be heard over the usual chaos. Consider something radical like posting your Scoop.it feed to your own site, or posting a link you found to a relevant forum where people are already discussing the topic. (Use your Scoop.it link instead of the direct link).
A quick trick for sharing to Twitter from Scoop.it
Twitter is my social media feed of choice. However, this means I am careful about what I post there when it comes to having a real post versus sharing and promoting anything. So, I get extra bang for my buck when I do choose to share a link from Scoop.it.
