The common belief is that Snapchat rules all when it comes to evaporating photo essays. But the numbers don't quite back it up. Instagram has announced that over 200 million people are using Stories every day to share quick moments from their lives -- almost 50 million more than Snapchat as a whole sees in an average day. Snapchat's 158 million count is from its IPO filing in February, but, the app's entire user-base cresting 200 million in two months seems pretty unlikely. Of course, 200 million is still only a third of Instagram's user-base, but those aren't bad numbers either considering the feature launched last August.
