Sneaky. The Follow button appears to work, and persists across partial refreshes, but an actual browser refresh shows that nothing happened. I'm honestly not sure if the sneakiness is a UX bug or intentional.
Great observation
Getting a refresh loop on the page and the follow count is going up, 5072 and climbing fast.
It's down to around 3k now.
On a seperate note, the X site doesn't even work for me. Something about adblocking is breaking it I think.
