Playing in cyberspace

I spent a large portion of Sunday playing in cyberspace – setting up a twitter account, overhauling my blog, chatting online, downloading a new program, and doing a bit of web surfing.  It was fun, but I don’t know that it was particularly productive.  The conversation was interesting, and I learned a few things in articles I read, but I wonder about the use of time.  Most likely, I should just accept it as fun and not worry about it, even if I do sit in front of a computer for a living.  Seems like I ought to have more active things to do with my time off.
