Ok, so here I am trying out W.Blogger, I still have Visual Bloggar installed, and of course have Internet Explorer as a backup.
each application I've tried seems to have some nice features, it would be awesome to get the following into a single application...
Spell checker (w.bloggar has this) - very nice!
Image upload - including images in a blog is painful - the images need to live on a web server somewhere
Direct HTML editing (Visual Bloggar does this quite well)
Comment Reply - I'm typing a new post for "My" blog, why can't I also read any replies to previous blogs and also post my comments from the tool - since functionality like spell checker is already there... (in some apps)
I'm sure there are other features, I will add to the list as I go along...
