No... no objectspaces, but MSN Spaces! and no O/R mapper, but a blogging site! 
. Of course, I created a spot, err... space, over there: http://spaces.msn.com/members/fransbouma. I'll use it for off-topic rambling, but I'm not sure if anyone will ever visit that blog 
. Oh well...
The site is very slow though. Doing things takes aaaaaaaaaaages. I hope this is due to the beta state, otherwise it's not that good advertising for ASP.NET...
