It's very hard in life to keep friendships up, people grow up and change from a month to month basis and unless you've got regular contact with people they quickly change their lives and exist without you. I don't really recommend adding people on Facebook who aren't on the surrounds of your social circle. But what I do recommend is bumping into people at parties and events and adding them. You need to be adding people you meet on Facebook, its Important you introduce yourself to people using your FULL NAME then they are inclined to give you their full name back. Shake their hand and be formal but also fun and then you can have all their details to later add them on Facebook, ask what they do and where they are from to ensure you add the right person.
The day after meeting people you should add them on Facebook without explanation and avoid the first conversation when you see them online the first time, the next time you see them hang about wait until they've been online for several minutes, then say 'Hey' don't jump into explaining yourself,
