I happened to read one of the many junk e-mails that I get from Microsoft (I get them on purpose) and saw this tool for posting to a blog. I thought I would try it out. I just downloaded and installed it, but I haven't read anything on it yet. I thought I would go with a "trial by fire" sort of approach.
It looks like you can do standard blog tasks with it, such as insert tables, pictures, maps, tags, or hyperlinks. I am just going to insert a hyperlink to the download.
