To see this plugin in use, it’s probably easiest to watch <a href="http://www.pling.org.uk/static/Live_Blogging_for_WordPress_2.0.swf" rel="nofollow ugc">this screencast</a>.
Live Blogging is a plugin developed to support blogs that are doing live micro 
blogging of running events, such as major sport events or tech conferences. 
(such as the <a href="http://www.nouse.co.uk/2009/05/10/roses-2009-live-sunday/" rel="nofollow ugc">Roses sporting tournament</a> 
at the University of York).
Using WordPress 3.0’s custom post types, the plugin allows you to create these 
micro blog entries in a stripped down version of the normal post edit screen. 
These micro blog entries then get included in a post which has been activated 
as the microblog.
By default, the plugin uses AJAX polling to allow your readers to instantly 
update what they are viewing, including any new comments posted on the post. For 
professional bloggers, Meteor is supported, which gives the smoothest updating 
experience for your viewers and also significantly reduces the load on your 
server.
Additionally, the plugin also supports integration with Twitter – if activated, 
the first 139 characters of each live blog entry will be posted to Twitter when 
they are made.
Using this plugin will give you an advantage over your competitors if you’re 
blogging from live events – your readers will get updates quicker, and it will 
integrate into your blog better than competing systems, such as CoverItLive.

Narwhal Microblog adds a minimal front-end posting form on any page with the shortcode, [narwhal]. It’s meant for short updates or microblogging.
The form submits without refreshing the page and then redirects to the post that was created. If you don’t quite like this behavior, check out the FAQs.
Unlike other front-end forms that have you type out the title, post content, and tags separately, this plugin takes an original approach by using a special format. Think of it like using markdown in a way (if you’re familiar with that). Once you commit the format to memory it makes posting updates even faster.
What you type into the textarea is:
(Title in parentheses) 
Content on a new line with any word #hashtagged.
Example:
(This is an amazing title) 
But, the #content is even better!
The above would create a post titled, “This is an amazing title,” with “content” as a tag.
