Wow its working :D.
Drivel look promising, no need to login to web for posting blogs, now I can blog using Drivel from my Linux desktop.
To install Drivel on Fedora all one have to do
sudo yum install drivel
yum will take care of all the dependencies. Once install launch the drivel from Application-Internet menu.
And then login to blogger.com or any other blogging site by entering your credentials.
And then start blogging right from your Linux desktop :)
