*Veteran lurker posting opinion*
I think a responsive site is a good move and folks will be pleasantly surprised. However, Nikos (hey dude! long time no see), yall might consider keeping the app "shell" as a gateway. I've seen sites that do this and as long as the site is designed right most folks won't even know they are just going to the regular site. The issue is a lot of us (myself included) have gotten used to the single entry point of an app. And while the argument might exist that it's just as easy to open a browser, go to favorites and select LHCF from the multitude of bookmarks you have, it's just as easy to forget the site exists without the physical presence that an app provides. Out of sight, out of mind...
I was gone for a long time until I discovered the app. If I don't have the visual reminder, I forget it's here.
