Techno "now"

OK - so I am a little late in the virtual, techno craze. But, I joined facebook today. Wow - - so many people I haven't seen or even thought about in years! The world really is a small place. It's fun to scroll through the albums of my friends and see their families. It's weird to suddenly have digital conversations with people I haven't spoken to in 10-15 years. I'm impressed. Now - can I keep it up and stay involved and up to date? We'll see.......
