I’ve always agreed with this, but most of the people developing OSM work for companies. If these services were baked into osm.org, then those companies would likely have issues.

As someone else put it, you can go in that direction and end OSM’s commercial prospects or try to make osm.org’s purpose (that it is for mappers only) as clear as possible.

Fantastic idea. I nominate the fantastic KiwiIRC web client if you were to go ahead with this. It’s far superior to qwebchat and its (largely outdated outdated) ilk.
