I literally fell upon this service called facebook. It seems quite popular amongst the populace in the States, but I seem to have found some people from Poland too.
I guess it's just a friend making and informing tool. You can show them your pictures(unlimited upload and quite fast), tell them where you're going, see what they're doing and generally communicate. It looks something like Yahoo 360, but no crappy blog and no overly creative designs.
I actually found some people from LaSalle Academy, my primary school for 5 years in Shillington, PA. Cool:) Exactly what I was looking for:)
