Like many people, I have lots of Facebook 'friends' who I never speak to. I left school 13 years ago and I still have people on from there, even though we haven't spoken since and wouldn't speak if we walked past each other in the street. This is also the case with uni people, work colleagues and people I've met on holidays, who I still have on Facebook.
I have noticed some people have removed me, and while this feels a bit of a snub, I suppose it's fair enough as we are strangers now...
If I culled the list down to family and people I actually speak to, I would probably have around 30 'friends'.
Do you delete people or do you just leave it as it is?
