Sometimes you can find something useful in a morass of utter garbage. The key is to only visit when you really need something you can't find anywhere else.

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.
