First off, s9y kicks ass. I've tried many blogs , from plog to wordpress and your work of art is quite simple the easiest to install and manage; the most stable and has the most predictable behavior.
That said, there's one feature that none of the blogs I tried (including s9y) have. I want to blog about different subjects. It would be really nice to be able to do this in several independant blogs. And it would be really convenient if blogs could be added via the admin interface.
Granted: s9y has categories, but that's just not quite what I need. I would like the blogs to be totally independent, though possibly linked to eachother through the sidebar. I can't do a shared installation, because my host won't let me have multiple virtual hosts. And wouldn't it be cool if even average users could setup multiple blogs with s9y, ie without having to edit config files?
I really feel this is one of 2 features that will firmly consolidate s9y in it's position as undisputed leader among blog apps. I won't bother you with the other feature right now, cause it's even more of a long shot
Thanks for your time,
Jeroen
