it depends on the team as well to market the project correctly. but investors and fans can do their part as well in spreading this.

I agree, the team should promote the projetc and develop a good product. If the product is good users will be happy and will recommend it to more people.

Especially for social media users are the best promotion. If the social media is good, the user should spread the word and recommend it to their friends. That is how Facebook, Twitter and Instagram also got a lot of people in the beginning. Currently I see a lot of people talk about Vero another social network which also a lot of photographers start to use recently.

When I used to use Facebook (in Facebook's early days) it wasn't polished either they only improved it overtime and took several years to become what it is now

Even though I don't use Facebook, it will be really interesting to see if and how it can adapt to the changing market.

Yes you are right, even it will take some time to takedown the facebook, it will eventually happen. So SPHERE can thrive beyond them.

Btw. Ios app updated 4 months ago, any planned updates on IOS?

I sent referral link to my friend before several days and he gets next in his attempt answer - there is no more referral program on Sphere!
Is it really works now?
Thanks
