I've had blogs on LiveJournal, Wordpress, Blogger, Posterous and Tumblr, and here's my view on the difference: Livejournal: The proto-Facebook, for personal blogging and sharing your thoughts/lives with your friends, with a personal connection with the people who follow you. Wordpress.com/Blogger: Mainstream blogging, letting you share your opinion with the world. I switched from Wordpress.com to Blogger because they inject ads into your blogs. Neither have great editing interfaces. Posterous: Mainstream blogging simplified, I switched from Blogger to Posterous because it just works. I can write a post insert images and it will come out looking decent (on Blogger/Wordpress I have to spend far longer tweaking layout, etc.). Tumblr: Single media micro-blogging, Tumblrs support for mixed media blogging is very poor, you have a photo or a block of text, but not both. It's much more about community as well, it's closer to Twitter than to the other blogging platforms. It's all about followers and re-blogging other peoples posts.
