Oh sorry I didnt recognize you answered that quick!
I found the theme called The Erudite on this side:
Its created by Matt Wiebe: http://somadesign.ca/projects/the-erudite/
The Erudite theme is well created for a writers ambition. I love the pure look of it, the clear sheed and the typography. Its really worth a look.
Still it has all blogging features, but one can emphasise the literary aspects very nicely. So its a blog very comfortable for readers, too.
Now ison.at is a wordpress 3.0 Host-Blog ...but I would prefer to stay with wordpress, because I got a better feeling with wordpress... it's all perfect here... I'm very satisfied... Also I'm not sure about ison.at. For many reasons wordpress is more erudite to me... ;)
It would be great if you add that theme one day cause I fear Im one of those writers who dont have a clue about CSS and all that selfmade technique..
Thanks for the support
