For me discovering new projects has always been by perusing these forums.

Anything that doesn't even announce itself on BitCoinTalk always seemed to me to probably be such crap that they preferred not to expose themselves to the kind of expert scrutiny denizens of these forums can bring to bear.

You still have to be careful about what you invest in. Many people on the forums shill junk projects that they are invested in. They want to dump their bags on you, they want to use you as exit liquidity. Do your own research before you buy anything. You have to do your own risk assessments, you are the only person you can fully trust to cater for your own financial well being.
