Does that not depend on whether you are working for yourself, or as a 
part of a cooperative project? Do you not care whether others can use 
what you store? If you are simply working for yourself, please use your 
own database. If you are happy to share with millions of others, please 
acknowledge that there must be a certain level of governance to stop OSM 
resembling a landfill site.

Nobody limits *what* you map, but if you map things which have a broader 
significance than your personal hobby, then there may be 
rules/conventions/guidelines on *how* these features are represented 
within OSM. And if such governance does not yet exist, it  should be 

Currently there is little governance within OSM. This situation cannot 
persist much longer or the whole project will implode. Anarchy will 
produce "WOM" - Write Only Memory - whereby everybody adds their own 
little bit of information using their own ontology, resulting in minimal 
data quality. Mappers can do what they like, and users of the data (in 
decreasing numbers?) do their best to make something useful out of the 
ratatouille. The size of the main database will be much larger than 
would be needed with stricter data modelling, resulting in sub-optimal 
performance, which once again will tend to frighten people away. So 
let's just accept that some degree of restriction is 1000% inevitable.
