I really like live writer. I love online/offline applications that have both a software and an online component - I get the best of the experience with the best of the reach. Anyway, I've already talked about that and that's not what this post is about.
I really like some of the new features of Live Writer.
My favorites are spell checking (which was notably missing in the previous version), the new category picker (why can't I create a category though?), the icon next to the weblog (its the little things too) and my personal fav is the "Set publish date" feature.
I tend to post in spurts and its always bothered me that they turn up in a cluster and then I appear to take a holiday from blogging for a week. Now I can "manage" that better :-)
The only problem is that with a blogging engine based somewhere in the US and me based here in NZ time zone, there is a bit of guessing as to when the post needs to be set to appear...
