Now I can post to my twitter account from emacs (my favorite editor). Just install twit.el and you are ready to post to twitter, check recent tweets, etc. Download the twit.el file to some directory in your home dir (I have it in my .emacs.d directory) and then add the following line to your .emacs file present in your home directory.
(load-file "/path/to/twit.el")
After doing it and restart your emacs, just press M-x and twit-post and type in whatever you want to and press enter. It will then ask your twitter id and password - which gets saved for the entire emacs session. It is a very basic authentication and is not secure.
By the way, FSLog too has a twitter feed. You can follow this feed to get updates when I post here. Thanks to Srid for this tip.
