What's wrong with their UX? You click on a category to narrow the scope and then search using the searchbar. The only time it is an issue is if you aren't sure what category you want or maybe you aren't quite sure where you live.
Listings can be a mixed bag, but that's entirely user data so it's hard to fault Craigslist too much. IMHO it's better than having some 5 page form you have to fill out every time you list something which people will just screw up anyway.
