>>2016908The threads originally began to share content known to be new/recent, that is, with the intent that anyone could contribute so long as the content was new. The person known as DOT DOT DOT accounted for the vast majority of its content for quite a while, and so the images tended to reflect sources where he deigned to check for new artwork, and thus reflected his tastes (the "thick" content you reference). Others have and do join in and post, but most of those who do seem to do so in part because they have similar tastes.
