Best Free Blog

Dunno if this should go here or the help forum.

I'm setting up a small presentation concerning blog use for a few people. I have already set up things like the motivation, good guide lines, etc. However, I want to have a run through with one or two blog services.

I have been looking into blogs (and have used some in the past), but wanted to see which one was the best in your opinion.

Note the following:

There needs to be some options of who can see what message. Like, everyone, friends only, and private.

It should be as user frieindly as possible.

If possible, it would be nice to upload small videos and pictures.

Customization is nice and welcome, but doesn't outweigh simplicity. Yes, we all can do a lot with various Blogs,but the group of people I am talking to range greatly in computerish abilities. Also, the harder it is, the less motivation there is.

Jam it back in, in the dark.

Whoa! Okay, I must have confused people...

I am not setting up a blog server (sorry for the confusion). I don't have the resources. I am looking at blog sites (i.e. Livejournal) to see what is the best, simpliest and cheapest (and by cheap i mean free) one for people.

In other words, I was wondering what was the best (or some of the best) of blogging sites currently available.

There's nowhere I can't reach.
