Twitter taps celebrity 'curators' from Amanda Palmer to William Shatner

But is it curation or commerce when the collections that you are compiling mainly feature your own products?

Twitter's latest new feature involves celebrities and brands curating "collections" of their favourite products and places for their followers on the social network - although in some cases, their lists are decidedly self-promotional.

"You'll be able to browse rich collections from influencers you care about and get more information about the products or places you find interesting," explained Twitter product manager Amaryllis Fox in a blog post as the feature went live.
