Why it matters: Investors were initially bearish on Snapchat after Instagram launched a rival "Stories" feature, which put a dent in Snap's user growth. But now Snapchat is proving that its focus on engagement over scale can lead to more opportunities for advertisers. A recent analysis by MarketingLand shows that advertisers have more opportunities to reach 13- to 17-year-olds with ads on Snapchat than they do on rival properties, like Facebook or Instagram.

One philosophical thing: Snapchat is focused on connecting people with their top 5-8 closest connections. Facebook COO Sheryl Sandberg told Axios' Mike Allen last week that their strategy is the exact opposite. Facebook connects people to their "weak ties," or people they aren't close to, Sandberg said.

Why it matters: In a time of unprecedented colliding crises for the nation, the polling considered Biden to be vastly more competent.
