It's About the Big Picture
'Imprecise' is one way of putting it - 203,000 in lieu of a more accurate 202,986 views. 'Order of Magnitude' is another way of looking at it.
Excessive detail, especially in a social medium designed for quick scanning at first, creates too much distraction for negligible informative gain. The fact that in the above example 114 nonexistent views were generously rolled into the total number of views count adds little benefit (the difference between the precise count and its rounded surface equivalent is less than 0.1%).
Flooding users with overly precise numbers in this context can be pedantic.
Anecdote time: I attended a presentation once in which a fairly junior product manager presented revenue figures from his product line to a few execs, and his presentation cited numbers in the millions down to the last cent. The big cheeses, user to consuming lots of figures on a daily basis, and knowing how to tell the black from the red, started cracking patronising jokes at the poor fellow about his nickels and dimes. It did not occur to him to aim for the opposite effect by rounding the numbers on his presentation (e.g. $ 16.4 M) so as to make them instantly consumable, and memorising the precise figures - albeit down to 100s of dollars only - only for the eventuality of being asked, in which case he could have impressed them by showing how on top of his game he truly was.
Moral of the story: Detail distracts.
Conventions for Multiples
Abbreviating thousands as 'k', millions as 'M', etc. is an anglocentric habit, and should be handled with reserve before a global audience, such as addressed by social media. Even the use of commas and full stops in larger numbers is obverse to the English convention in many languages. Although given that decimals are absent from this context most ESL speakers will quickly figure out how the purpose of the comma separator in English numbering, and especially in US-centric social media platforms, differs from their native custom.
Sense of Time
Humans think of time as an order of magnitude scale as well. 'An hour ago' is meaningful (as fairly recent), as is 'earlier today' or 'yesterday'. Listing a precise h:mm:ss counter instead will make the recency of a posting harder to map mentally and presents the consumer with unnecessary cognitive noise. Does it really matter if the post was 58 minutes and 15 seconds, or 61 minutes and 9 seconds ago?
Where everyday human perception of time is concerned, excess precision is most definitely annoyingly pedantic unless of course it really matters, as in a departures and arrivals schedule, sports (even there I find a delta measured by 100s of seconds ridiculous), and, of course, higher physics or rocketry.
