You deserve them all. Contributors who post quality content deserve those followers. While it is great to acknowledge where you remember that there is always something more. Don't stay content with 500 followers strive for the next big number that is attainable in your mind. Do not aim for a million followers next rather perhaps 750 or 600. Psychologically that does wonders, it's similar to the state of flow. Look that up if you're curious it is very interesting.
Yup definitely! I celebrate each 100 followers because in a way I want to thank everyone who like what I have to say and support me.
