Took the Twitter authentication fix (by cheche) and added some code to add the live blog url to the Twitter update and created a new version of this plugin, since there don't seem to be many good live blogging plugins available, and the plugin author seems to have abandoned this project.
You can download it here: http://vidyut.net/downloads/
I will try and submit it to the repository So that there is at least one alternative for live blogging that works on WP 3.8 (without embedding a live blog hosted elsewhere).
I am not experienced with coding, so no idea how the submitting process happens, in the meanwhile this plugin works with WordPress version 3.8 and tweets the status update with hashtag (if any) and link to liveblog without any problems. I am using it at http://aamjanata.com
