I nominate @photocircle, a curation initiative for the photography community. The are variety of posts for this account, a curation report post (not original) but in addition there is also "Photocircle Digest post" (original content) where in photography insights, tips & tricks are being discussed - @ocdb votes will only be used to promote the Photocircle Digest post.

I hope you consider @photocircle to be on the whitelist @acidyo. Thanks!
