Live Blogging

To see this plugin in action, you can watch this screencast: http://www.pling.org.uk/static/Live_Blogging_for_WordPress_2.0.swf

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 Roses sporting tournament 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.

New2WP Author Box

What this plugin does is utilize the WordPress dashboard profile section, which is so very neglected to my knowledge. It will replace the Yahoo IM field that most people may find rather useless, with a Twitter field.

Authors can then add their Twitter name, if they choose, and using the other existing fields they can add their URL to their website, with a little blurb about themselves in the biographical info box, and obviously their email address. It’s very basic, but does the job for most multi-author sites.

Admin Management Xtended

As a whole, the new WordPress Admin panel is organized fairly well, however when it comes to editing posts or pages quickly without having to open each post or page in a new tab or window, it isn’t a very efficient process. For those who are using WordPress as a CMS, it’s important to be able to manage contents easily and quickly. That’s what this plugin helps to do.

It adds some icons to the posts/pages management panel with AJAX-driven CMS-known functions like toggling post/page visibility, changing publication date and title without having to open the edit screens or reload the page, plus changing page order with drag’n’drop, inline category management and inline tag management, plus much more.
