The Actor Atlas includes several pages on EU:

In some cases there is already a Spundge note-stream curating content from across social platforms when it is tagged with #isicEU for posts on economic activities and #cofogEU for posts on functions of government1.

If you want your Twitter tweets to be included in the note-stream below, send a direct message to @wikiworx.

In Facebook and Google+ make sure to post public when using the tags.
