I have registered a tumblr blog and trying it out. Tumblr is a form of blog that uses short form of posts. Posts can be text, video, images, audion.
What I have found useful is the i-phone application. The application allows photos, texts, audio and links to be uploaded. Works well. Images upload fairly quickly.
Tumblr would be quite useful as a tool for reflection of work practices.
