Keep in mind that OpenStreetMap is a data project, not a maps.google.com replacement project. There are plenty of other ways to look at OSM data.
https://tiles.mapbox.com/newmap and
http://maps.cloudmade.com/editor let you style the data yourself,
http://open.mapquest.com/ lets you route and search across it.
https://github.com/mapbox/osm-bright is a good start at building your own style.
http://osmbuildings.com/ uses CSS to draw 3D buildings based on OSM data.
http://bl.ocks.org/migurski/5130639 renders it in your browser with WebGL.
The tiles shown at openstreetmap.org are meant as a tool for mappers to help with mapping and are not our product.
