There's a new addition to the top of Reddit's homepage: trending subreddits. It's so small that — like some of Reddit's most incredible little-but-growing communities — you might not have noticed it. The "front page of the Internet" is calling attention to its fast-developing forums, hoping that their reach will spread as fast as some of the most popular subreddits. AskReddit  and IAMA  have well over a million subscribers each.
Today's trending subreddits are /r/minimalism , /r/oddlysatisfying , /r/showerthoughts , /r/JapaneseGameShows , and /r/h1z1 . Below, we've collected a few lesser-known subreddits that are equally homepage worthy.
Chemicalreactiongifs : If you're looking for a cool way to kill time, this subreddit is the perfect way to while away minutes. You don't need a chemistry background to enjoy the GIFs and videos of the coolest chemical reactions. Gaze in awe when you watch a close-up of a kernel of corn  popping in slow motion, or find out what happens when lava interacts with ice .
SubredditDrama : This is where all the Gossip Girl-like action happens on Reddit. If you're looking for some dirt on "abusive moderators, internet fights and other dramatic happenings from other subreddits," this subsection is for you.
FindaReddit : Looking for a subreddit that suits your needs? Just post your request in FindaReddit, and readers will suggest subsections that may apply. For example, if you're looking for a special reddit for studying  or one that will give you gift-buying advice , just post in FindaReddit and there is usually a commenter who'll offer some suggestions.
Needadvice : If you want advice for a problem you're dealing with, check out Needadvice, a subsection that has almost 9,000 subscribers. The community seems to be pretty active, and you'll have a higher chance of getting more responses in this subreddit versus one that has hundreds of thousands of subscribers. That's because your submission can get lost in subreddits with too many posters.
AskCulinary : For cooks who need some guidance, you'll get to pick professional chefs' minds in AskCulinary. Find out what went wrong with your dish, or just learn more from others on how to cook.
PerfectTiming : Photography nerds would love this subreddit that displays once-in-a-lifetime pictures or videos that happened to be caught on camera at the right time.
Terriblefacebookmemes : For every clever Facebook meme, there are dozens of bad ones. Check them all out in Reddit's terriblefacebookmemes, a place where Facebook memes hang their heads in shame.
