Do you ‘un-friend’ people?

I’m going to write a fairly off topic blog here.

I have tons of ‘friends’ here.  I figure that they’re a little less ‘close’ than my subscriptions, but I still enjoy randomly perusing their writings every now and then.  Sometimes I find someone I enjoy enough to start a subscription with, and that’s encouraging. 

However, there are some ‘friends’ that I constantly get updates on that I really don’t want.  I’m not interested in seeing what they have to talk about, and I don’t really want to follow their thoughts throughout the day.  Xanga still doesn’t offer me the option of deleting items from my universal inbox… so when there is a blog topic or picture that I’d love to just not see any more… there is nothing I can do about it!  Except, that is, the option I have to un-friend.

Is this something other people do?  I usually end up feeling rather guilty about it, but at the same time… it’s my inbox, right?  Have you ever un-friended someone because you didn’t want to hear or were offended by what they had to say?
