It seems like a giant confidence game to this day. 80% of adults in the US don’t use Twitter, and of those that do, only a much smaller number are regular users, and an even smaller percentage care to follow brands, which most people rightly see as opt-in advertising. The timeline algorithm makes it even less likely that the pointless post from @reebok is going to reach many people, probably nothing close to the amount of free irl advertising that they gave to Twitter and Facebook.
Yes I’ve poked at twitter a few times but never saw the point. Have been drowned by news of them for almost a decade, right? Self promoters and journalists just desperate for “engagement” to their own detriment.
