Like button

<p>A like button, like option, or recommend button is a feature in <a href="/facts/Communication_software/j4AsfGL4">communication software</a> such as <a href="/facts/Social_networking_service/qFIh6VT1">social networking services</a>, <a href="/facts/Internet_forum/bRuqfQfN">Internet forums</a>, <a href="/facts/News_website/MCA3yt4E">news websites</a> and <a href="/facts/Blog/bb6awu2X">blogs</a> where the user can express that they like or support certain <a href="/facts/Content_(media)/eW5vd3Dr">content</a>. Internet services that feature like buttons usually display the number of users who liked the content, and may show a full or partial list of them. This is a quantitative alternative to other methods of expressing reaction to content, like writing a reply text.  It is the most used feature on social media. 
</p><p>Some websites also include a dislike button, so the user can either vote in favor, against or neutrally. Other websites include more complex <a href="/facts/Web_content_voting/VK8R5xLk">web content voting</a> systems; for example, five <a href="/facts/Star_(classification)/kmdyt6Y3">stars</a> or reaction buttons to show a wider range of emotion to the content.
