Embedly (YC W10) releases new version of their API
blog.embed.ly
blog.embed.ly
Something to do with embedding content not just a link. What do I do from there? Your call to action button is a link to the api and the jquery plugin goes to a github page where I have to checkout the repository to try the demos.
I was searching for exactly this service for my social network startup. Found Embedly, navigated to api docs, went live in just an hour or two. Great service, I almost forgot it's there until seeing this thread.
But the documentation was clearly written. I figured out how it works after reading the first page.
One note to Embedly: the first example in your documentation includes a link to a blogging site that no longer exists. You might want to change that so your customers do not think your service is old or abandoned.
