Facebook?

So one of the technologies i though about using was Facebook.

I thought Facebook would be a good idea for a few reasons.

1. Basically every one i know has Facebook, including my parents who are who i need to speak to. 
2. Its free 
3. Its an app for smart phones, again something that basically every one i know has. 
4. Its easy to use
5. It provides notifications when something new happens 
6. You can create an event, so i could create my event add my parents and use this as the place for discussion

I then thought about some of the disadvantages 

1. My parents aren't always on Facebook , and don't always hear the notification 
2. It is not as private 
3. It doesn't have a video option which would be helpful for me to have to physically show my parents my ideas when it comes to things like venues and decorations
