My search for a Linux desktop based blogging client ends here..
Blogilo is the answer….:)
On ubuntu install it is very very easy. Just do
# apt-get install blogilo
Once done open the tool and configure your site for blogging from Settings->Configure Blogilo->Blogs->Add
The autoconfigure worked like magic….
If your behind your corporate firewall and still want to use Blogilo make sure you edit the file ~/.kde/share/config/kioslaverc and append the following to the file
[Proxy Settings][$i]
ProxyType=1
httpProxy=http://username:password@proxyserver:port/
httpsProxy=http://username:password@proxyserver:port/
ftpProxy=http://username:password@proxyserver:port/
The moment I gave the above info in the file , it started working like magic 
Here you go my first blog through Blogilo
