Here's a comment I picked up today from the Blogger User Support Group on Yahoo:
Take a look at http://bloghorn.com which I now use after having tired
of Blogger going down so often and no useful responses to problems
but usually simply NO reponse. (Something that didn't/hasn't changed
since Google took over ... odd given Google seems to be generally on
the ball with its other services.) Whenever I've needed help Bloghorn
responds quickly and helpfully ... a case of where "less is
more", "small is beautiful" or whatever other appropriate cliche you
want to call upon.

We had not heard of Bloghorn before, but will probably add it to our comprehensive review of blogging software that we are preparing.
