I think the site still matters a lot.  It's the first one and better than anything that may follow, should someone else come along with a future gpn blog.  Def keep it going.  If u have less time for it, spend less time on it.  But don't shut it down.  Of course if u have real reasons and priorities, and u have no choice that is one thing, but don't end it just cause the band got famous.  That's the whole reason u started the blog!  U knew that day was gonna come didn't u? Also I think Facebook will be dead in 3-5 years. Wil just be a big bullshit advertising thing that would essentially be useless for most of us.  Ride out the storm brahh.  Keep the blog going.  The band is obviously into it, if its been around 5 years...so until that changes if it ain't broke don't fix it.
