Invisible mode

Gtalk and the invisible mode!
I think people should not be given that chance of staying in the invisible mode. If they want to be hidden from people they don't want to talk, let them remove them from the list. Why is that mode needed where you can see everyone online and ping them at your will? It basically is the center self important status. When you are not respecting others' will.
Too much into just a feature in messengers. But there are many who agree with me. All the angels who stay online, not being invisible.
PS - one could argue about the busy status and chatting. :D
