The Steam app for Android shows a number of new categories that have little to do with gaming, which could be a shred of evidence that Valve is considering different kinds of apps for its popular game distribution service. The "Genre" section of the app's index lists genres like "accounting, education, software training," and "photo editing," with a total of ten additional categories over those shown in the Steam desktop client — though none of the categories contain any software. There's obviously no guarantee that this means Valve intends to sell more than just games, but it's not unreasonable to think that the company might someday go down that road: it's already working to streamline the selection and release process for games on its platform with Steam Greenlight, and could conceivably do the same with other software genres.

Thanks, Daniel!
