1) yes, through affiliate links. most marketplaces give you commission on sales.
2) yes better filters/ more infos is on the roadmap. getting data of ~4000 themes is not a task i want to do by hand. and the infos i get by scraping the sites is limited. but as someone said before, the user doesn't care about how its done, the user cares about how it works. so i'm going to think about that. maybe i let mechanical turks look for all that data.
but for now: there is a filter for responsive themes. its the layout-> responsive layout filter. if you select that, you will get all the themes where i definitly knew that they are responsive.
