I've been on a hunt for cool InfoPath-related blogs; well, I just found a gem. Shoutout to Liam Cleary whose blog talks about SharePoint, VSTO, Groove, and, of course, lots and lots of InfoPath. I loved all the screenshots and detailed walkthroughs. Some highlights:
1) Article on Word import - a walkthrough of a new feature in InfoPath 2007 that allows converting Word documents into InfoPath form templates.
2) Very interesting article on picking the right technology for your project: Word + VSTO or InfoPath.
