I help maintain hip.porn and am reviewing the mobile experience of its Russian-language latest-video feed. I would appreciate specific usability feedback rather than a general rating. On a phone, is it clear how to move from the latest feed to categories and back without losing your place? If you would change one thing first, would it be the filters, the category labels, or preserving the scroll position? The site is adults-only (18+), so please open it only if appropriate.
