Pro and contra of course there is. several persons said The cause of staying in front of monitor while chatting, photo share , information share or just looking around, sometime will forget meetings, party, relationship, even for many person they're late for working. For example, when someone sign in in one social network and start to chat each other, sometime they reluctant to cut this moment. But for the other reason, many people don’t care about this, even they dare to release a lot of money to pay internet connection just for this social network. They feel happy and give reasons that join in this social network is pleasing and add knowledge.
Beside confiscating much time, we have to confess that the social network can give benefit for us, such as promote our self, promote our ability, promote our website or our own blog, untill introduce and sale our product. The other benefit is our creativities will be increase, because we wanna to make and use many tools and application to improve member area and to make our social network more attractive. When we try to use this application and tools of course we have to learn and find related topic from many sources, by asking our follower,asking our friend or find it from search engine.
So, is social network for relax or for learning? I think for both of them...
