4. stackoverflow is user hostile towards rookies/newbies.
People and mods forget s that it is not easy when you are new and everything is new, you dont know exactly how things works, what to search for because you dont know the exact words etc etc. For someone new that wants to learn programing it could be very complicated to grasp everything. Even if it is a simple question or maybe stupid question for someone that is experiensed, an anwser could still be very useful for someone new to understand something and could dayes and weeks to finally figure it out by theself. Now people just downvote and closes questions supereasy and that could be very demotive to learn programming.
Ok if "experts" dont want to read all newbie questions, but there should be a tag or something you could click so peolple now this and dont just downvote and close so easy and so people that dont want to read those question can skip them and people that want to be more helpful and understand its a newbie question still can help before everything gets closed or whatever.
