Reddit chat rooms are here. As if you didn't spend enough of your 9-to-5 workday browsing /r/aww, /r/explainlikeimfive, /r/bestof, or /r/SubredditDrama, you can now share your thoughts about posts (and life) with real Redditors in real time! Mashing the F5 key to refresh a static comments page is so last year.

You open what looks like a bill, but it's just junk mail. You click through a donation process too fast, and they turn your one-time donation into a monthly contribution. A snack's packaging makes it look bigger; an opinion poll is obviously one-sided; when you copy-paste a line from an article, the site adds a "read more" link for your "convenience." Don't express your impotent rage alone. Take it to Reddit's /r/assholedesign, a place to expose and discuss evil design tricks.

Away from the Trump supporter spam and creepy fake celebrity porn, Reddit is still home to uplifting conversations, useful information and weird-arse videos. The key is, and always has been, subscribing to the right subreddits. The Lifehacker team shares our favourites below.
