Hashtag is a very useful thing to unite all messages connected with one selected topic and it's currently used on nearly every website. When we are using hashtags, then later it's easier to find content which we want to check. Thanks to the latest update YouTube improved the operation of its website thanks to the use of hashtags.
After new update we can find hashtags located above titles of videos on YouTube. YouTube automatically will choose three first hashtags from description of video which was done before uploading a video. By clicking on each from hashtags we can check all content described by exact hashtag. New option isn't too big change, but surely will allow for more comfortable using of YouTube.
