Always the disproportionately vocal cancerous lesions of online communities. Even before the mod boycott, I've preferred that subreddits go read-only to keep content (when it qualifies as such) easy to find, not risk admin-purging, and sectioning off the late-comer horde from degrading any residual standards.

I've been irritated that the only sizable center-right tech communities I've found are the *chans, which are almost too much chat-room for my forum.
