It strikes me that social media users place an awful lot of emphasis on gaining big numbers of followers.
And indeed being able to say "! have 100000 Twitter followers or I have 50000 Instagram followers does sound impressive.
The question is how important is it to have a big number of followers?
Well, I believe it is not as important as you might think.
Let's say you have a Twitter follower who has a 50k following.
A retweet would indeed have a lot of value as you are potentially shown to a much bigger audience.
