I think that’s where the gap comes between why I would participate in something and where others might. I can’t see where the ‘fun’ element comes, apart from enjoying the gaming aspect of it and, as you say, tribalism.
I’m not asking these questions to be negative. I’m genuinely interested in why people would vote on something like this. Not people like @Michael or @anon5422159 or local business owners who see the benefit of raising the profile of our borough and by implication our local area, who can hope to make new social media connections via participating and as Chris said, generate a bit of publicity. But there is no prize, nothing to incentivise the average Twitter user to vote for their borough.
Especially this week of all weeks, I’m aware that while participating in social media survey and polls might be ‘mindless’ it’s certainly never entirely without consequence, even if those consequences are overly benign.
