Windows Live Writer
I'm uploading this post using Windows Live Writer and it's really comfortable.
It automatically loads the style of the blog so you can also know what it looks like when you edit it, and it loads all of the tags from the blog.
It's got tons of plug-ins like:
- Polaroid Picture - add a cool Polaroid style to your pictures.
- Paste from Visual Studio - easily transfer syntax highlighted source code from Visual Studio to elegant HTML.
- and many more
Only problem I have noticed so far, Is the inability to insert local videos (Via the blogger web page I can upload my own videos and blogger converts them and creates an embedded video stream).
