Twitter likes are easy ways to show someone you agree or approve with his or her tweet. Whenever someone reads something he or she likes, they’ll usually place a like to show to the writer appreciation.
Using twitter likes in a twitter conversation can be a good way to show what you think or feel. It’s not always easy to get what you really mean across when involved in an online conversation. Most of the time, to emphasis your understanding on what the other person says, you’ll like his or her statement.
Twitter only allows 140 characters so if you’re in a conversation, you may go back and forth instead of typing a long explanation like you could on Facebook comment field. When you’ve reached the end of a conversation, you may not know what else to say so often, you’ll use likes to end a conversation. You can also place likes to cushion a blow when a person is saying something aggressive. The writer would know that while you have different opinions, you could still appreciate what is said.
