Robert Morris lists some helpful tools for writers, authors and bloggers. I have tried Evernote but haven’t found it that helpful for my uses. My daughter (who’s 18) loves it! I use Hootsuite and think it is helpful and user friendly. The Elements of Style book Robert mentions is pretty basic. It is a fast read and gives you good information, but I think there are a lot better writing style books and websites out there. This one has just been around forever. Scrivener is a helpful tool for writers and so is Jutoh. I use Jutoh. Both are important for authors wanting to convert word text to mobi or epub formats.
