I I've been knowing Wattpad since late 2012 but I made account on early 2014. So for some times I've been become a purely silent reader (because I read story without an account, and I was sorry for that ) then I realized every writer deserve to get an achievement for every story they have written by giving them a vote. If you can't criticizing or giving advice you should at least give them a vote and perhaps many votes. Not only commenting "please updating the next chapter" or the worst one is "where's the next chapter ? I've been curious, update sooner !" only a moment after the new chapter published. They need your advice and criticism for their story so they can give you way better update chapter, if you don't have that capability a simple vote really works for their writing spirit.
This is my humble reminder for all the reader (as same as me) to keep supporting the story you like by giving comment without pushing for next update also remember for always voting on every chapter and story. Trust me, if the writers are happy and pleased, then they will give you many better stories later. Please remember that !
PS : for every writer, keep your working and just ignore that harmful and unsympathetic comment about your work. You deserve many "nicer" readers. Happy writing
