I'm glad that I'm able to share my insights about it.
Reblog on contests is a common practice that I noticed here in the platform. It's a good way to boost interaction among users.
Hmm I may try to host a contest in the future as well. We'll see if I'm able to find a free time for it 😁
Hosting a contest? I think those who host contest are consistent. Therefore, people are checking their profile often. I think you can start with weekly one if you have a lot on your plate at the moment =P..
Good luck,
