Apparently they come in waves. The blogosphere is waiting for no less than two new blog systems. There is Textpattern from Dean Allen. And there is Postmaster by Dan Benjamin.
Textpattern promises to be simple, easy to install and packed with lots of text editing goodies to ease your writer's life. Postmaster compares itself to, simply, the three best known blogware in an intriguing road map: it will first run as a hosted service (à la Blogger), then as a desktop application (à la Radio) and eventually as a complete server software (à la Movable Type). With such parenthood, it better be good :).
Still looking forward to a weblog editor done in Flash though.
