2019

Management's Discussion and Analysis of Financial Condition and Results of
Operations
Key Metrics, page 64

1.     You added disclosure in the risk factors that you restated your active
user data for periods
       from the fourth quarter of 2016 to the first quarter of 2018 but were
unable to restate your
       user data for periods prior to the fourth quarter of 2016. Given that
you present active
       user data for the first three quarters of 2016, which are calculated
using your prior
       methodology, please disclose this prior methodology in the filing.

FirstName LastName
         insight into the extent to which historical financial information is
indicative of future
         results. In order to provide further context to the nature of your
historical growth in light
         of the early stage of your monetization efforts, please quantify how
both the number of
         advertisements placed by new advertisers and the increased number of
advertisements
         from existing advertisers have impacted the change in revenue. Refer
to Item
         303(a)(3)(iii) of Regulation S-K and Sections III.A and III.D of SEC
Release No. 33-
         6835.
3.       You indicate that your analysis relates to the amount of revenue based
on the geographic
         location of your users. However, it appears that the geographic
revenue you disclose
         correlates to the amount disaggregated based on your customers'
billing addresses. Please
         revise to discuss the changes in geographic revenue derived from the
location of your
         users.
Unaudited Quarterly Results of Operations Data, page 73

4.       Please ensure that your discussion of historical share-based
compensation expense and net
         income (loss) throughout your filing is balanced with a discussion of
the substantial share-
         based compensation expense you will incur in the future, in addition
to the cumulative
         share-based compensation expense that will be recognized upon an
Initial Event. Clearly
         indicate that your results of operations subsequent to the completion
of the Initial Event
         will be significantly impacted by the recognition of share-based
compensation with
         respect to the vesting of unvested RSUs as well as any newly issued
RSUs. In this regard,
         revise the footnotes to Summary Consolidated Financial Information and
Other Data,
         Selected Consolidated Financial Information, and Unaudited Quarterly
Results of
         Operations Data related to the amount of share-based compensation
expense included in
         historical costs and expenses. Indicate that future share-based
compensation expense will
         affect your ability to achieve future profitability.
Description of Capital Stock, page 149

5.       Please revise to provide a more detailed description of the material
voting rights of the
         Class A common stockholders. For example, disclose the circumstances
under which the
         Class A common stockholders are entitled to a separate class vote
under Delaware law or
         under your amended and restated certificate of incorporation.
Consolidated Statements of Cash Flows
Supplemental Cash Flow Disclosures, page F-8

6.       We note that your schedule of non-cash investing and financing
activities includes the net
         decrease in accrued property and equipment additions for the year
ended December 31,
         2018, which would appear to be a cash outflow. Please revise to
clearly identify only
         those transactions that do not result in cash receipts or cash
payments. Refer to ASC 230-
         10-50-3.

7.    Please revise to disclose an estimate of the financial effects of the
subsequent events. For
      example, you should indicate the grant date fair value of the restricted
stock units granted
      after January 1, 2019, as well as the related impact on share-based
compensation expense.
       In addition, disclose the expected effect on the balance sheet upon
commencement of the
      lease related to the agreement entered into in March 2019. Refer to ASC
855-10-50-2(b).
