One of the biggest problems users have when choosing Linux, is that they are unaware of some of their existing possibilities for a specific purpose. In this case, the instant messaging for Linux It is one of the points where we realize that the user does not know all the alternatives that are being offered.
We are going to make a small list with some of the options that we have so that you can find and use the one that you like the most within the Linux environment.
Pidgin is one of the best clients of instant messaging for Linux with which we can connect to many other programs (AIM or MSN, among others). The only problem is that it does not have native support for voice calls or videoconferencing, although it does have a plugin to “cover” these deficiencies.
This program is one of the best options if we are not interested in any other communication protocol. We can make videoconferences or voice calls, for which you will have good support. aMSN is very reminiscent of Microsoft's MSN Messenger, so that users who come from the Windows environment are usually the ones they use the most and the one they are most comfortable with ... well, the option is there.
Kopete is the homonymous version of Pidgin for KDE with many possibilities, and with native support for videoconferencing, which is a point to keep in mind.
We have given you some options, then you are the one who chooses which one you like the most.
