I like it when old threads are bumped. If it's something that's going to cause a heated debate that will never end then it's pretty pointless. But those ones aren't bumped too often, and it's pretty easy to ignore them.
I find that since people who have been keeping snakes for 20+ years are still learning, I don't mind reading a 2-3 year old thread that is loaded with information. Snakes are my passion, and I love to read and learn about them as much as I can. I know alot of people on this website also share that view.
