Are you searching for an IM client? This is a fun process, but only if you end up with what you really want. Some people know exactly what they are looking for in an IM client and have no problem finding it. Others, those who are not as informed, usually have to take more time to find what they are looking for. It does not matter how long it takes you to find the right tool as long as you get what you want in the end.
What you want in an IM client will determine where you turn. For instance, if you are only looking for something basic to use at home there is not much to think about. Choose an instant messenger that you know a bit about, and let it guide you through the setup process. The features list probably does not matter too much.
Of course, there are other people who need more from their IM client. This is definitely true among companies. If you need a good application for use within your company it is important that you do your homework. There are a lot of options out there, and all of them must be considered. Do you need an IM client with a secure network? One that allows you to chat? Do you need to send files quickly and efficiently?
What you want in an IM client does not have to be the same as everybody else. As long as you get what you are personally looking for you will be happy and productive soon enough.
