Roughly one year back, Google released its popular instant messaging application called Google talk which allows one to communicate with others, similar to the ever popular Yahoo Messenger. Initially Google talk client was available for Windows users only and people using other operating system such as Linux had to do with using the window which was embedded in their Gmail account. The problem was that to use Google talk, you had to log into your Gmail account.
Google has not yet released a native build of Google Talk for Linux. But what has changed is that it has now released a flash version of Google Talk which works in the same manner that an Instant messaging client is meant to work. The convenience for the Linux end user is that now in order to send text messaging using Google talk, one need not log into ones Gmail account but can directly access the Google talk interface as shown in the images below.
