If you were looking for a way to create a Pinterest-like board, that can integrate web sites, images, video clips and files, and that you can embed within your content, like this, then you should give a good look to LookBooks.
LookBooks is a web service which allows you to curate embeddable visual information boards in which you can organize all content types.
A LookBook looks somewhat like a Pinterest board in which you can manually arrange individual tiles and integrate multiple types of information items, alongside your notes and comments to tell a story or to contextualize the different items presented.
LookBooks can be easily shared, published on the LookBookHQ web site or embedded on any site or blog and can be easily measured in terms of traffic and usage analytics.
Free 30-day trial.
Paid plans (targeted at enterprise customers): $250-2500/mo
My comment: There is a long-standing and growing need for a curation tool, that while extending Pinterest style visual collection abilities provided the ability to manually arrange board items, to include information objects beyond simple images and to be embedded on any web site or blog.
LookBooks fulfills therefore a growing need that Pinterest may not be interested in leveraging yet. Unfortunately LookBooks has chosen a pricing strategy and free-trial strategy (someone has to contact you to get you in) that cuts it out of getting any early traction through early adopters and, as a consequence, I think it may remain a model for other newcomers to exploit more than a useful tool that I can recommend you to take on your toolkit right away.
