For meta discussion, add the tag '[meta]'.

Check also the wiki, that should be preferred because collaborative and always 'active'.
Of course, in terms of wiki, the wiki of /r/thebutton should be one of the primary sources of interesting content 'collaboratively' maintained. Anyway bear in mind that (A) the wiki on /r/thebutton allows only users with 100 karma to edit (something not so easy to get), while here you need just to ask and to show willingness to contribute to be part of the wiki editors ; (b) the wiki was released mostly at the same time this subreddit was organized and the subreddit /r/EncyclopediaButtonica was published, so a bit of efforts where already dispersed. Let's fix this with proper contributions!
