Well, I don’t know if anyone else had the same idea (I am pretty sure that I am not the only one) but here is the thing: Wouldn’t it be just great if Google talk web gadget (as shown inside Gmail interface) existed in -almost- every Google service?
Let’s state the facts here. If you are using Google’s services like Gmail, Gdocs, Greader you may have noticed that Google talk (Gtalk) gadget exists only in Gmail web application. I personally think that its existence in both Gdocs and Greader is not only fundamentally cool and energy saving (alt-tab alt-tab) but also very very useful for you and your online friends.
