I see many applications and or software to write blogs however the windows live writer affectionately known as WLW is by far the best I have tried. In my test post it appears Blogspot and WLW work seamlessly at present.
If your worried about bow your post will look see the picture below for an example of the sophistication built into this great product from Microsoft.
Microsoft has done well with the latest version allowing competing companies access, Blogspot and WLW work for example. Also I love the cool interface as shown here on.
One of the best things about WLW is you can switch between blogs by clicking a post save have to open each site & going to edit. This saves a huge amount of time. I have also noticed the work and postings seem to flow a lot quicker as a result of not having to try to remember all those passwords addresses and the like.
In summing up if you are a serious blogger or a part time one you should really grab this software and use it's great features YOU WILL NOT REGRET IT.
