The osmarender software is the underlaying foundation which is used in the t at h project. What you see on openstreetmap.org (and informationfreeway.org) as the osmarender layer, is the output of the t at h client which uses a variant of osmarender.
Mapnik is a separate project from openstreetmap (although closely working with it), it produces beautiful maps (most would state that they are prettier than osmarender). The tiles you see when you select the mapnik layer, are produced from a mapnik installation with our custom homegrown style sheets.

That is what OSM is all about, yes. People have for example adapted both mapnik and osmarender style sheets to produce maps for cyclists.
