If you remove the advertising/financial connotations from the word "influencer", then I have been influenced more by people on Mastodon than any prior social media:

I now often go for bike rides when the weather is not perfectly wonderful, because of a guy who rides every day.

I've found, looked at, and intend to swim in the local ocean baths, because of a lady up the coast who frequently swims and posts pictures which make her ocean baths look pretty wonderful.

I've read several books because of people here waxing lyrical about them.

I've made a chilli dipping sauce, because a lady on here suggested that to me.

So, for me, the influencing on Mastodon is more … "authentic"?
