I would suggest to have your website compatible with https protocol. This will bring more credibility to your website and besides it's for your publishers security.
I have purchased cert but i have to migrate to another hosting. I think it will be done in this week.
However, there is no sensitive data in service. Hacker can't do anything except claim new sites.
Two months later still not done.
Doesn't smell good. Even if you consider that "hacker can't do anything except claim new sites", privacy of your users should matter to you.
I'm sure other people would like to try your services but are waiting for you to set up SSL.
