Vero looks interesting, but in short: I think the era where you have to pay to use a product is 'over'. The new era is: we get paid to use a product / produce content. Steemit is an example, but if we're talking about Instagram alternatives, take a look at steepshot.com (still in alpha, but on the STEEM blockchain) - or https://appics.com/ - another 'Insta alternative' with STEEM based crypto rewards :-)

I strongly believe the 'tokenization' of the internet via blockchains even means we will get paid to see sponsored content / ads in the future :-) Or watch a movie, or... Anything really.

These are exciting times and it will change the way we think about what 'social' media actually is :-) And what the worth of the content makers is.
