To delete or not to delete, that is the question

So I've been thinking lately about the pro's and con's of Facebook. I'm sure I don't need to make a list because most of you have facebook and probably have the same list I do. So I've been thinking, is it really worth it? It's really nice to keep in touch with people from my past and it's so easy to keep up with my family. But, honestly, maybe I shouldn't be clinging on so tightly to my past. I do have a life in the here and the now. So does having Facebook enrich my life or detract from my life? Living in the now, in my home, with my husband and kids and school and work and extracurricular and church and neighborhood... there are a lot of things that pull for my attention. I am thinking I should simplify and cut out the unneccesaries, the distractions, the complications. What are your two cents?
