Pinterest makes "browsing" fun for a lot of people and it works very well at that. Pinterest does show specific categories of content. A similar experience to compare is Google images, where you provide a keyword and get a similar infinite-grid layout. Not everyone is searching for something specific; if a user can browse (or view by keyword, as in Google Images) they can gain inspiration or direction toward a goal. Pinterest's UX approach is not worthless - it can and does work for many interaction scenarios where users want to browse content rather than search something specific. Further, I think the two UX paradigms (search vs browse) can work together to serve the needs of users. Search for specific content can provide exact results first, and then related/similar results can display in a browsable pinterest-style grid.
