I found the Google+ "what's hot" feed interesting too, until they went through yet another redesign and I couldn't find it anymore. I didn't have enough interest to ask the Internet how to find it again, so I slowly just forgot about it. Now I don't felt like I've lost any utility from not giving it three minutes of my time every day.

Unless you disabled it there are hot posts every half dozen posts in your home stream. The hot stream itself has it's own link in the left hand sidebar called explorer.
