Ah, gotta love it!Kylie Jenner says Snapchat is over - and Wall Street panics
The stock market value of Snap, owner of the Snapchat messaging app, fell $1.5bn after reality TV star Kylie Jenner said she no longer used it.
Ms Jenner told her 24.5 million Twitter followers: "sooo does anyone else not open Snapchat anymore?"
She was adding her powerful social media voice to the growing criticism of Snapchat's re-design.
Snap boss Evan Spiegel had something to soften the blow, though, with news his total pay was a huge $600m last year.
Shares in Snap fell more than 8.4% to $17.8, falling back close to the $17 price that the shares were listed when the company floated on Wall Street.
The disappearing messaging app was re-designed in November. But many users criticised the change, and one million people signed a petition.
Ms Jenner, the half-sister of celebrity Kim Kardashian, tweeted: "sooo does anyone else not open Snapchat anymore? Or is it just me... ugh this is so sad."
She did, though, later tweet a follow-up: "still love you tho snap... my first love".
Snapchat has rejected the complaints, with Mr Spiegel saying earlier this month that users just need time to get used to it.
The criticism from Ms Jenner was followed by news that Mr Spiegel received $637.8m as total compensation last year after the company went public.
It is thought to be the third-highest annual payout ever received by a company's chief executive, although the compensation package was heavily boosted by the award of shares in the company. His salary for 2017 was $98,078
The package trails the 2007 and 2008 compensation packages for Daniel Och, head of hedge fund Och-Ziff Capital Management.
He received an annual compensation of $918.9m in 2007 and $1.19bn in 2008.
What power (and how fickle must investors be).
The money will probably come back for the most part but still - amazing to see such influence.
