Online journal and cloud

Live Journal is ranked as the No 1 online journal service by topreviews.com. Penzu is a close second.  Nobody mentioned Blogger but I do find out it has the same private journal option as Live Journal.  At the same time, one advantages of Penzu is its "encrypted" entry feature.  However, after searching some time, I still don't know what does that mean. Nonetheless, all three can claim that they are in the Cloud, which is where I started this search. Basically, here is the list that I really's wanted:

1. Web based online service;
2. Basic rich text editor with hyperlink and image functions,
3. Privacy control allowing a single user (i.e. myselfe) and potentially other (not sure why) users.
