Tumblr.com

Bloggers have long lamented the constant pressure to post daily, even multiple times a day, or risk becoming irrelevant or losing their audience. Well, it's Tumblr to the rescue: this service helps you feel good about your blog, even when you have nothing much to say. A "tumblelog," as the company home page notes, is more like a scrapbook than a journal; images and text are displayed rather large to help pump things up, and the posting process—basically working buttons on a "dashboard"—couldn't be easier. Vox also stands out among the many blog builders out there. This service, from Six Apart, lets you set a different privacy filter for each post if you want, so you can opt to make some of your blog public and other parts of it private.
