It's the ripple effect of things. A few great people have been submitting entries for 24 weeks now and from there we gain new people each week. Some stick around weekly, others when they have time, some only support the entries, and some don't last as they are looking for what is in it for them vs viewing this "contest" as a way to give back which is the focus. There are prizes, but they are small compared to the effort people put into this. So those who continue to enter are doing it because they want to give back and support the community.

That said if multiple people you follow are part of the contest it says you follow some good hearted people.
