Dropbox does file sharing better than anybody, I think. Share with yourself and others. Pay a small fee for a better product and know it they have an incentive to please you. You can use any software products when sharing with Dropbox. I have been happy with it for many years and have never had any problems, knock on wood.

For me, the key point of sharing documents in google docs is that it solves the simultaneous editing problem, which simple file sharing (Dropbox and others) does not.

You can easily have three people editing the same paragraph in google docs; whether libreoffice online is a viable alternative depends on how it handles that.
