I enjoy the warning in the footer:

"WARNING: This site has been known to cause a mind blowing experience. We recommend you prepare yourself mentally and if possible be sitting down. Side effects may include saving money, letting out a chuckle, and sporadic oinking."

Domain related: I regret getting a .io domain for my email and website; with the price increases, it's not far from $100/year. I'm looking to move from Namecheap to Porkbun and to move to a .com domain.
