Blogspot, also known as blogger I likethis name better. Wordpress. Tumblr which is yahoo's blogging network, various website builders. All blog sites are technically free trials, they all offer you a custom domain if you buy it. For example blogspot.readit to readit.com. You must pay for that. My personal favorite is blogger, google's site. It allows eay tracking and navigation as well as templates and color pickers. Other blog areas takes a little more "looking around" for what you want. So I go with the guys above.
try BlogSpot the Google site. it's free and popular.
I think that Blogspot.com and WordPress.com can be useful for you.
They was free, are free and will be free.
weebly.com
webs.com
sites.google.com
What are some good FREE blog sites. I want to have a blog site to share or keep track of my poetry, but have zero zilch money to spend on something like that. NO "FREE" TRIALS either... FREE ALL THE TIME.
