Hey! I'm one of the co-founders of Ozlo. Excited to finally to get to share him with you today. If you want early access, sign up here and we'll let you in:
Android is on our list, but for not for a few months yet. Eventually Ozlo will be in a lot of different channels - including messengers, the web, and Android.
Ozlo can work over any topic area we let him learn about. We focused on food for the reason you said, but expect to open him up to many new topics soon!
We use the VIP code because there are some times when you need to let someone in immediately (important partner, people that might be able to help us test a specific feature, etc.)
I think that in general incentivizing people to share by giving them a bump in line feels unfair.
