I finally migrated to Drupal 4 Blogger today. It is about time that I do this myself and eat my own dog food. Hopefully this would help to dig out the bugs but so far, so good! But I dont promise this to be perfect so please report any problem and bear with it for a while.
I look forward doing blogging without having to wait for rebuilding and without MT hogging 99% of the CPU when rebuilding. :-)
ps: Oh yea, migration is done using mt-to-drupal.
