I have also created my own space (blog is written in Finnish). After using it for two days the annoyances I have encountered is that sometimes I get the Finnish version, sometimes I get the English version after I log in (I would prefer the Finnish version). Haven't still figured out, how to view my page everytime in Finnish. Another issue which is related to this that I'm unable to view updated/new Finnish spaces if I wanted. When I log in and the content is in English, so are the recent updates/new spaces on the front page of MSN Spaces. Besides, is there a way to browse spaces by country and also to view all the spaces, not only those which are visible on the front page of MSN Spaces ?
 
OK, so this is beta version, but hopefully these get fixed soon.
