Hi (((((Liberada)))))) I haven't been on Facebook in ages, but I used to have two accounts. The other thing you can do is create separate lists within your friend's list. So, for example, I created a separate list of people on Facebook who I played games with - Farmville etc - and each time I posted anything to do with Farmville etc, I selected that list, so only those people would see it.
I hope that makes sense. At any rate, the idea is, that each time you post something on Facebook you can control who can and who can't see it among your friends. You just need to create different lists ("work friends", "game friends", "family", whatever) and then you select the relevant list each time you post so that only those people can see the post.
Or, you could just have multiple accounts, which is less work!!!!!!!!!
