Windows Live Writer (WLW) is an awesome product to help you write and manage your blog posts on most popular blogging services.
For me, it just got better with two new plugins I discovered today
1) Allow pictures to be added to the post and uploaded to Flickr simultaneously
2) Allow custom tags to be added so the posts are correctly categorized within my blog as well as other popular services such as technorati or del.icio.us
Good stuff. Guaranteed.
