The Most Popular Social Media Sites

These are the most popular social media sites ranked by monthly active users (for the most recent date I could find data for). The data is from various sources and is the most recent reliable sources I could find (Alexa ranks as of January 2019). What constitutes a "social media" site isn't so easy to define so I use a bit of judgement on what sites of involved enough of a social element to be included.

1. Facebook (monthly active users 2.2 billion - Alexa Rank #3)
2. YouTube (1.6 billion - Alexa #2)
3. WeChat/Weixin (1.1 billion - #2,537)
4. Instagram (900 million - #17)
5. Tencent QQ (803 million - #6)
6. QZone (548 million) - #209
7. TikTok (500 million - #3,204)
8. Sina Weibo (446 million - #18)
9. Tumbler (350 million - #65)
10. Reddit (340 million - #13)
11. Twitter (335 million - #11)
12. Baidu Tieba (300 million)
13. Snapchat (291 million - #4,480)
14. LinkedIn (270 million - #30)
15. Pinterest (230 million - #77)
16. VK (120 million - #14)
17. Huya (100 million - #565)
18. YY (95 million - #270)
19. Taringa (75 million - #811)
20. Renren (? - #1,824)
21. Nextdoor (? - #1,310)

Alexa rank doesn't track smart phone app use (Alexa tracks website use, and far from perfectly but it does provide some insight into how much use popular sites get). Most of the social media sites have most use via apps but many also have useful web sites. Some have much more of a bias to smartphone apps (WeChat for example).
