Looking for a place to aggregate your thoughts in a scrapbook fashion online? Tumblr is a simple microblog platform and might be just what you are looking for to post your thoughts, images and videos. Tumblr offers a six different types of posts which include: a regular post, quote, photo, video, conversation and link. Unlike other conventional blog platforms, Tumblr does not offer comments, thus making Tumblr more like a one way log than a conversation. Eric Rice calls Tumblr a hybrid of twitter and WordPress, but it is more than just that as you can integrate a number of feeds and thus create your own customized personal aggregator.
I created a Tumblr log called Totally Frank to aggregate my activities on Twitter, Stylehive, Last.fm and Flickr. You can find other Tumblr logs by tuning into the Tumblr Radar, an aggregation of recent Tumblr posts.
