Thank you for the mention :) You also basically beat me to the idea I’m working on for my next post. I think the bullets you spelled out above: social, curated roundups, linking to other content are having some really interesting impacts on how content marketing works.
For example, when I wrote the piece you mentioned above I had basically no audience, a few hundred followers on Twitter, that’s it. By writing it in a way that I was pretty sure would appeal to Mattermark Daily I was able to get it featured there, and now it’s heading toward nearly 10,000 pageviews!! In the old approach of, “build your list slowly over time”, this just wouldn’t have been possible. But now, people who have no list can reach massive audiences thanks to really great curators.
Also, on linking to other content — I feel like curation demands a lot of attention (big surprise, there are vendors in that space w/ $$ to make :) but information digestion tends to get far less air play. There’s so much opportunity in writing content that digests ideas for people. The value of sitting down and spitting out a quick post is slipping (unless you’re Seth Godin), but if you can be that next layer that joins disparate ideas together? You’re onto something uniquely valuable.
