Yes, I have observed one thing that by blogging you can improve your writing skills. Though mine is still improving, but I can see some minute changes so far in my English writing skills. You can also improve by reading other's blogs (like mine :P).
So, I encourage all my readers to go and start blogging. It is very easy to start your own. Simply CLICK HERE and register yourself, and your blog is ready.
If you are having any trouble in starting up the blog or getting confused with the interface, then you can always contact me at firstname.lastname@example.org
or you can chat with me on Yahoo! Messenger. My id is ppragith
