I installed Jitsi today on Linux and I think it is more powerful than popular clients like Pidgin. It provides out-of-the-box security for end users and that a huge plus to Jitsi.
As many knows, skype has introduced skype web <https://web.skype.com/en/>. I have tried it and it provides a similar experience to native skype clients. After the deprecation of SkypeKit <http://www.disruptivetelephony.com/2014/07/skype-shuts-down-skypekit-and-the-skype-developer-website.html>, many third-party applications have stopped working (e.g IM clients that supported skype then).
However, with the new Interface, it is possible to get text messages and there is already a plugin for Pidgin called skypeweb for pidgin <https://github.com/EionRobb/skype4pidgin/tree/master/skypeweb>. It provides instant messaging but it's not finished yet. The developer is working alone on this plugin (with others testing and reporting bugs).
I am not a developer, so I do not know about the possibilities of implementing (and maybe extending to audio calls ?) this idea. Security-wise, this is still skype.
All in all, I am a skype user and a new Jitsi user. It would be great to see Skype(IM) in Jitsi. I am thinking of making a transition to the Jabber network, but then I would lose communication with skype contacts and that is another issue.
Thanks for continuously developing Jitsi. It is extremely user-friendly and does a great job in security.
