It's the nature of the platform. It's not meant to be a place of discussion, really.
There are a few comments on many posts that are considered. dMBL40 always gets comments from other mums with SN kids who basically say Yep, me too, it's shit sometimes isn't it, keep on keeping on, you're not alone. And one can see how it's become much more than a business platform for her. And people like dear Orla who writes so beautifully about baby loss and has I'm sure been a great find for other parents who've experienced that.
So I'm not dismissing Instagram at all.
But with the accounts that are basically kids + clothes + holidays, the comments seem to skew differently. There's a lot of people basically throwing flowers at the performer on the stage. And I can't help but wonder what the effect on you that would have, 365 days a year. No wonder anything negative would be upsetting.
But anyone who puts a product from a "brand" out onto the market should welcome feedback on how that product needs to be tweaked. If a product is starting to irritate, you go back to the drawing board and listen to where people think it's gone wrong. Except on Instagram, where you can have so many followers that you never have to care that much. You've become too big to fail.
