Security is a non-issue if it's built correctly (sanitized input, user roles, etc.). Besides, this is a pretty simple use case so I don't think the web app would be too complicated to build or maintain.^it's a security thing. People try to hack their way through the site. We wouldn't be able to do it from scratch and make it as secure as we need it to be as well, which is why we use wordpress.
But yeah, we have some exciting plans for next year.
