Should I renew my ACM membership?

It’s that time of year.  Should I renew my ACM membership?

I just renewed my IEEE membership, including the Computer Society portion.
Communications of the ACM (CACM) is an awesome journal, but I haven’t really been reading it for a while.  I find much of the same content online in various blogs and other repositories.  Not all, but much.
So what do you think?  Help me decide.
