So, I had never been resteemed. But sometimes I resteeme posts by myself. You know, from an experience in the old platform like lg I can tell that there are 2 values of resteemed posts for your acc/journal: 1. You make a libreary of the interesting information for yourself, so you don't so thinking a lot about up-votes that it may bring you 2. Your libreary is really usefull and interesting not only for you. In this point you'll able to do even more points on the article than the author themself. It's like in a real life, I think. Everything depends on you ability of choosing and classification materials. Like a good bibliography that allows you to get the information without waste time
