Most unlikely that you can connect to Facebook or Twitter using an old G3, as you cannot run the latest versions of Flash Player.
Running the old Jaguar won't help either, you need at a minimum Leopard 10.5, and only a G4 or above can run that.
I am afraid that you are stuck in the past!

You need to upgrade to Tiger 10.4.11 to get nearer to the modern internet.
might be cheaper to buy a newer Mac. Look at the mac mini. best would be an intel mac min.
