That's nice... but as you'll quickly find out, that number is pretty much meaningless. What you should focus on is how many active followers you get. The reality is that many followers will never interact with us. Either they are bots or they don't really use the platform regularly.
Now, if from those 500, 10% or more are actively engaging with you, congratulations! You're doing very well! :-D
Yeah true it's a meaningless number as I saw a lot of bots following me. But it's fun to stand still at the milestone and appreciate the few that really follow :)
I hope 10% is really following ;)
Thanks!
