TECH CRUNCH - Pinterest is up against a credible threat with the rise of TikTok when it comes to social commerce. These days, the more common refrain among influenced and inspired shoppers is "TikTok made me buy it," not "I found it on Pinterest." But the company reported fairly solid earnings, pulling in $575M in revenue versus $573M expected, and delivering earnings per share of 10 cents instead of the 4 cents expected. But one troubling area was its decline in users. The company reported its global MAU decreased 9% from the same period last year to 433M in the quarter, below expectations of 437.9M.
