Tumblr
I tried a number of tumble log packages before finding tumblr and none of them ever really captured my attention. I could never find anything that could give me the ability to produce something like Anarchia (which if you don't follow, you should start immediately). But tumblr made all those failed experiments fade away into the haze that is my long-term memory.
It gives me a place to put all those camera phone pix that I don't want to upload to Flickr.
It gives me a place to put link that I don't want to put into delicious.
It lets me just post quotes from web pages. And by "web pages" I mean Fake Steve.
It does all this with what can only be described as a magic bookmarklet, without which tumblr would be just another "web 2.0" site that I would quickly abandon.
