As for your site, bmaier's suggestion is good, but if you are concerned about speed maybe you can do some ajax request on some local cached copy of the latest headlines?

I am using Safari 3.
If you don't get what I am saying I could try to rephrase it somehow..
As for your own IM client, users might be reluctant to download a new one unless there is a really good reason to download it (and to start it up each time you start the computer). If there is no good reason to be on it, then they might not. But you said that they'll have motivation to use it so I guess it should be fine. But if the motivation is that their friends are also using it, then getting their friends to use it too might be a problem.
In general I find 3 or 4 is a good number for a start. It's not too many to manage, but not too few. 3 is company.
It might be good to look into the mathematical side of the algorithms though, so that you know how they work inside. This way, you can manipulate the algorithms and fine tune it to something you want later on.
