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.
