You may know all about this already, but I just got one of those new Nokia phones with Lifeblog on it, and I must say I'm using it quite a bit more than I thought I would. Then I read more about it on Nokia's site, and found out that TypePad partners with them, but apparently "anyone can make their blog service compatible with [their] software." At the very bottom of this page
is more info, plus a document, "Lifeblog Posting Protocol Specification".
I know you guys are working on all kinds of other stuff, but this would be a really cool addition--Nokia is rolling out a lot more phones like this, and especially the N73 has turned out to be a damn nice phone. And no, I don't work for them.
