A favorite rejoinder of mine, when invited to participate in some activity in which I have no interest, is "No thanks, I have better things to waste my time on." When prompted to enter a description for this blog, that’s the phrase that popped into my head.
I hope I can provide you with “better things to waste your time on” than Facebook or WoW or ICanHasCheezburger or whatever you count as your current favorite timesink, but whether I can or can't, this blog is aptly titled, isn’t it?
