staff you are literally making your website harder for people to use.
That isn’t hyperbole or over reaction.

You swapped the ‘post’ and ‘close’ (cancel) buttons.

You removed the formatting bar & hid it in popups.

In short, you are changing fundamental parts of your interface to appear “sleek” or “edgy” or whatever other reason you have behind the decision.

But in the process you are turning a blind eye to your users that are negatively affected by such fundamental changes.

In particular, the lack of a formal “beta test” (as far as I am aware) is particularly telling, as it is indicative of an arrogance of knowing what your users want without bothering to ask. Transparency in social media staff decision making is vital in maintaining trust with your users.

staff you are simply not trusted by your users. You have deserved this mistrust on multiple occasions.

And you are going to lose your user base.

You are not facebook. You are not embedded into society; there isn’t a tumblr page for my local dentist. The only incentives to remain here is content & social circles. BOTH of those can be relocated to literally anywhere.

Already there are websites being formed promising a better, more accessible, more transparent-decisions, more feedback-fueled experience. AND ways to migrate data. (And tbh, even lacking a data-migration ability, people can do things manually just fine.)

With your reckless actions, staff , it’s not a matter of IF you lose users, it’s a matter of when.
