I think it´s really strange that Mumblr does´t have the possibility to make Facebook, Twitter och Instagram account a part of the blog. I mean it´s really important to be able to share your update on social media if you want people to read it. The possibility to share, like and maybe comment would be great. Hope to see it on the next update. I have´t found any good blog-solution with Adobe Muse where my customers can login and make a update.
