I like how easy it is! It's so simple, anyone can use this software - you don't need any skills or technical know-how at all (yet!). You really only have one option when adding content from external sources into your website/blog; there are no other options available in terms of importing images etc. If someone has never used such an editor before then they might be confused by some aspects e..g where do we save files? Where does everything go after editing / uploading them onto my site? How will users find these files once uploaded if not linked back correctly?! Also as mentioned above there doesn't seem much choice outside just using what comes already installed through WordPress itself which again could confuse newbies who aren't tech savvy enough yet. However since most people outsource their websites anyway maybe they should think about looking elsewhere instead of relying solely.
