I don't know exactly how it can give a better chance of finding new ICO, but I see some sites like icodrops, cryptorank,... and media like tw, fb, ins, tg,... But honestly, I don't think ICO is a wise way to approach new projects.
There are so many criteria that not all of them fit the understanding of every market participant. I find with projects that are built on temporary trends, there's not much to worry about and you only pay attention to the value that it can achieve the highest with valuation. As for the larger cases, the transparency factors in the operation process, such as products, team, roadmap, tokens, partners,... are carefully considered.
