So, I was having a little think about this. Some people hate updates due to the fact that there is no easy way for modders to update their mod, and because of this, some mods have been discontinued because the modder does not think it is worth the hassel to update. So, how can mojang fix this problem? I think one way this could be done is by adding a feature into minecraft that is a "built in modloader" and it can update the code it needs to for the update on the fly, but then again I am not quite sure how easy this would be to program due to how many different ways you can code a mod. So, if you have any input on the matter, please comment below :D (I may of missed stuff out but I was tired when writing this sooooo that's my excuse :P)
