Can Anyone explain what Tumblr is?

I don't have one but I have seen ppl go on and I just looks like instagram but on your computer. All I see are pictures and stuff. That's the best explanation I can give you.

i dont really konw but i do 爱情 this tumblr pege link

It's a website where 你 put up pictures 或者 视频 或者 fanfics of fandoms 你 love. Other people do the same thing and 你 can follow them and their "blog", like what they post, 或者 "reblog" things they posted.
Pointless but fun, funny, and addictive.

Tumblr basically is a website where 你 can have your own blog (or 更多 than one, however these have some restrictions) and people can follow 你 and 你 can follow them back.
Most of tumblr is "separated" in 2 sections: hipster blogs and fandoms. But there are also those blogs who are in between.
Nevertheless, both are great fun and 你 won't regret it if 你 加入 tumblr.
If 你 have any questions, tell me (I have a tumblr).

Tumblr is a plataform to create your own blog. And 你 can literally find all kinds of people in there.
Warning: extremely addicting.

Tumblr is a website that has over a thousand pictures of whatever 你 want. 你 can download 或者 share pictures. It's just like Instagram, but online.

I just made one last week and im still not clear what it's for and how it works. 哈哈 sorry
