Among the swarm of media aggregators, only a few really stick out. And of those that stick out, very few are reputable enough to be frequently quoted by the news and other websites. And of that very small selection, only Reddit can boast at having a userbase as big as it does.

With an estimated 6 percent of American adults using it, Reddit is not the small community it once was. The reason for this exponential growth since the site’s founding in 2006 is its growing base of experts and celebrities. These super-users have chosen Reddit as a way of gaining support or free advertising for whatever cause they want, and quickly.

Reddit is frequently graced by celebrities like president Barack Obama, Bill Gates, David Attenborough, Bill Nye, and Astronaut Chris Hadfield even once had a live AMA, or Ask Me Anything, live from the International Space Station (ISS).

No other community has Arnold Schwarzenegger as a moderator on its fitness board. No other website has Snoop Dog/Lion/Zilla post on a daily basis.

While Buzzfeed and other sites have a mobile application designed by the websites’ creators, Reddit has a fanmade app called Alienblue on iOS, and several others on Android. The fact that Reddit’s mobile apps are run by fans means several things. The first is that the apps are free and also constantly being updated, since there is an entire community, or subreddit, behind their development.

Second, the app has no advertisements, popups or any of the other things smartphone users have come to expect, because the community just wants a good way to browse Reddit. For people who have trouble with the Reddit interface, the mobile app is often considered even better designed, with a simple interface and voting system that makes it easy to get into.

For people looking for a way to waste time, and maybe learn something, Reddit is the ultimate solution. With subreddits on every topic under the sun, Reddit is the perfect media aggregator and website.
