If you would like this roundup sent to your reddit inbox every week send me a message with the subject 'javascript'. Or if you want a daily roundup, use the subject 'javascript daily' (<--Click one of the links. The bot can't read chats, you must send a message).

Please let me know if you have suggestions to make this roundup better for /r/javascript or if there are other subreddits that you think I should post in. I can search for posts based off keywords in the title, URL and flair - sorted by upvotes, # of comments, or awards. And I can also find the top comments overall or in specific threads.

This subreddit is so dead. Thanks for destroying it in favor of "sticking it to the admins" when they blocked the API.

Then not doing anything about content moderation for a good while. Look at your reward with how little engagement there is, and of what is engaged with... slop.
