It looks like you’re using the same domain for the app and user generated content? You usually want to host the user sites on a separate domain because the whole domain can be penalized in search engines for the content users create.

Yep. I also own tipsio.com but I figure for remembrance/launch reasons it's not super big deal right now. SEO play has not happened yet.

More importantly, user content can read and write cookies from the subdomain to the parent domain.
