My co-worker Noel Jackson, tired of hearing me whine about the Six Apart TypePad Trap, has created a WordPress importer mashing together the MT formatted export file (missing permalinks) and the broken TypePad AtomPub (missing comments and trackbacks). We are currently testing this on WordPress.com before polishing the code up and sharing it. We are looking for some TypePad customers to help us test it — it’s completely harmless, read-only.
If you are interested, let me know and we can set up a private blog on WordPress.com for you to import into. Bonus is that you will have a backup of your blog ready to go live if anything ever befalls TypePad.
