Choqok is a KDE microblogging client. It supports a number of microblogging sites like Twitter, StatusNet (which powers Identi.ca) and, with the new release, Open Collaboration Services. In my opinion, it is the best Twitter clients available for Linux - its far better than Gwibber.
The first release candidate of Choqok 1.0, codenamed "Huma" has been released a few hours ago. It will probably be the last release before Choqok 1.0 which is scheduled for release on 26th December.
This release brings a number of improvements over the previous beta release. Five new plugins are included - including a plugin to set your latest post to status message in IM clients. Support for Twitter lists has also been added with this release. You can view the complete changelog here.
Choqok 1.0 RC 1 is already available for Kubuntu 10.04, 10.10 and 11.04. You can install it from a PPA or you can download the .deb file directly and install. Since the PPA contains other experimental packages, I suggest the other method. Anyway both methods are given below.
