Tumblr - is slightly different from other blog platforms in that it encourages short content rather than massive ramblings.
The Telegraph.co.uk reviewed Tumblr saying; "...the smart thing to be doing online these days is tumblelogging, which is to weblogs what text messages are to e-mail - short, to the point, and direct."
Using their system, for free, you can set up very clean, uncluttered blogs with a host of features and elegant themes. They also allow you to post information and images to your blog directly via e-mail, so you can send material directly from your mobile phone. Of particular interest to artists will be their 'photo sets' feature which allows you to combine images and post them in image 'galleries'. If you like 'uncluttered', this is the one for you.
They have over 130 million blogs on their system with almost 60 billion posts. That's a lot of information and some of it might be interesting.
