Some background: Curating has been around for a long time as people have crafted scrapbooks, mix tapes and playlists. Thanks to the social web, we are capable of curating information in new ways.
Curating on one social web channel is similar but rarely the same as on another channel. On YouTube for example, one can create a playlist including one's own and other videos. On Flickr, a gallery is be default images one creates from other accounts. You cannot slip in your own photo in your gallery.
There are ethical questions to consider. To what degree is one able to exclude one's images from being pinned on Pinterest or flipped into a Flipboard magazine?
To colleagues who are artisans, chefs and other physical creative types, I recommend making it easy for me and others to curate visual imagery about your work. If there are ways to access details, it's good marketing.
I honestly don't think there are many thing nerdier than explaining 'curation' and why it might be useful. That said, your suggestions are welcome as we improve this presentation of content curation creation.
