Introduction of a follow option at the main IMDb site

I know there's a follow option here at the IMDb community site, but why isn't there one at the main IMDb site? Could you not merge this site's functions with your main IMDb site's functions? Or if you can't merge sites, could you please introduce a similar follow option there? 

A follow option at the main site would be useful for users to follow the reviews of people whose reviews they enjoy reading and would like to see more of in future. At the moment, there's no structural way of us doing that. It would also enable us to follow the lists of people whose reviews and ratings closely match our own, so that we have solid recommendations from people with similar tastes. You already have the functionality to show us how closely another person's ratings match our own, so it seems a shame to waste that data by not enabling us to follow those users.

Please consider. Thank you
