I see this thread is about a thousand years old but somebody has revived it.
The issue I have with "blogs" is unless you are following a person's travels in real time, a blog reads backwards. You can't read from top to bottom, you have to find the first day, read it, then find the second day, read it and so on. Sometimes you have to go back to a menu to find the days.
What I do is write each day in a Microsoft Word document. I'll copy and paste that day's writing to Facebook in a group that's limited to people I allow. Obviously, that doesn't prevent one of those people from reposting it but that's pretty unlikely. The only reason I want to limit who sees where I am is because I have a land home and I don't want strangers to know that I'm gone.
When I get home, after the cruise
, I take the MS word document, which now has a section for each day, format it into columns, insert photos and both print it and publish it on my brother's business website. At that point, it's open for anyone to read and I publish the URL and invite people to read it.
BTW< I have to fix the first page. Scroll down to see the cruises.
