Data which are significantly enhanced by the users (I know, it 
is hard to define what is significant) would be valuable for me 
as well. Basically I do not care about rendering but I have an 
interest in plain data. I am after interoperability without a 
need to import everything into OSM first. I would like to do 
spatial queries from the database and through web services and 
see what features and what tags OSM users have recorded around 
a given place and do comparisons with data from other data sources. 
But I fear no single tag nor a simple tag combination can ever be 
used for finding the real user contributed data and I will need 
to preprocess OSM data somehow.
