Anything on the net is temporary, look at the Yahoo disaster as a good example
Probably a few thousand years of collective human effort got lost with that debacle
Look at Wiki, which used to be amazingly interesting and has now been edited into the ground by a cabal of crazies
So if you find something good on the netty, enjoy it while it lasts because it won't last
I had a little gambling site on the net many years ago and on the last day of his presidency George Bush signed off the anti internet gambling bill and that was me locked out forever more, Ady the international criminal with the DoJ crawling over his tiny 40MB site
Its a funny old world and the internet is no exception
