Facebook is the world's largest social networking website that is played by almost everyone. Behind it, do you have any curiosity about Facebook facts?

With the number of users who have almost no more, already too much data compiled up from its users. Social networking application made by Mark Zuckerberg is definitely have a variety of user data ever published in it.

In other words, Facebook knows a lot about you. But the question is whether Facebook uses the data correctly or not. 

Facial Recognition

When a friend tags you in a photo uploaded to Facebook, then the photo will go into the pile of data mounts belonging to Facebook. This social network has a bot called Al. The function of this AI is to do a pattern that suits your face.

Facebook algorithm is claimed to have a high accuracy of 98%. In each uploaded photo, this social network is more accurate only in the face matching pattern. Just hope Facebook does not sell our faces to people who have malicious intentions.

Facebook Always Watches You

Making People Lonely Be Lonely

This fact may sound pretty sad. The reason, a psychiatrist from New York University, Dr. Sudeepta Varma, explains that Facebook makes someone know what other people are doing, but besides that Facebook also makes people more lonely.

Surprisingly in this study, mention that the use of Facebook for two weeks alone can reduce the level of subjective happiness. This is the reason why you do not have to play Facebook long.

Facebook Know More About You

The News Feed feature on Facebook allows users to engage in it for as long as possible. During that time, Facebook will collect your personality from what content you like.

This data will be used to target Facebook ads to suit the interests of its users. So do not be surprised if Facebook knows what you're looking for.

That was some facts about Facebook that is quite unsettling. What can be drawn from this discussion is: You do not have to play for too long. Use Facebook as necessary and do not make Facebook as a place to vent and so forth. The real world is still much more cool than the virtual world anyway.

Hashtag is one of the most important parts of social media. You certainly have often seen posts of friends or relatives who use hashtag, be it on Facebook, Twitter, Instagram and Google+.

But the question is how this hashtag affects these four social media. Are the functions and effects the same or any difference.

What is Hashtag

Hashtag is a word or phrase without spaces preceded by a # sign. This is one type of the metadata tag.

Words or phrases written in posts on social media services such as Facebook, Instagram, Twitter or Google+ will be tagged when given the # sign.

By using hashtags, they will be grouped into other postings that use the same hashtag.

Hashtag will also be a keyword for search engines.

The Influence of Hashtag on Twitter

When you log in and view posts on Twitter, it can be seen that most tweets have their own hashtags, especially company-owned tweets for business. Why is that?

Because tweets that use hashtags will be twice as viral than hashtags.

But keep in mind, never use hashtag more than two pieces in each tweet. This is based on research that says that:

Using more than two hashtags will decrease their effectiveness by 17%.

If using 1 or 2 pieces will increase 21% more effectively.

Twitter users will share or retweet as much as 55% if only use 1 hashtag only.

25% of tweets will be shared without using hashtags.

If using hashtag, will be retweet as much as 40%.

Influence of Hashtag on Instagram

Instagram is completely different than Twitter. In Instagram, the hashtags can be likened to a king and Instagram users usually use many hashtags in a post.

Based on Quick sprout research, an Instagram post that has 11 or more hashtags will get the best reach of 79.5% per thousand followers.

If less than 11 hashtags, the result is less than 50%. In essence, Instagram is very fond of posts that have a use lot of hashtags.

Influence of Hashtag on Facebook

The use of hashtags on Facebook is relatively new and not as effective on Twitter and Instagram. If you want to use a hashtag, just use 1 or 2 times only, because Facebook is not too fond.

This is because, the use of many hashtags on Facebook will look unnatural and overly impressed.

In addition, Facebook users are not too concerned about hashtags on Facebook because they use them only to interact with people who are familiar and interesting in their opinion.

For that it is strongly recommended to be careful using this tag.

Influence of Hashtag on Google+

The interesting thing in Google+ is, the hashtag will be there automatically, even if you did not add it to a post.

You can edit or add it yourself, but Google+ will usually predict which hashtag works best for each of your posts.

Essentially hashtag has become a keyword or keyword.
