Giving a like without opening the publication is the same as doing nothing, if it is true that it is very important to leave your like in the publications if you like its content and if you do not like it, leave your dislike, but what happens if you do not open the publication and do you like? Well, nothing happens since the notification arrives and you know that someone liked it and the one who just liked it is third and when you click it takes you to your same publication, that's why it's important to open the publication and comment on it.
