I think with this last comment you are moving into an area that Microsoft will decide (of course they will probably take comments into account) when they create forums for the RTM product.
My reading of the present situation is that these two forums are only for the Preview product - and thus match the two main areas Microsoft have defined for their support and documentation, namely ITPro supported by TechNet documentation and Developers
supported by MSDN documentation.
I don't see that it will be at all practical after RTM to only have two catch-all forums and thus these two (and having only two) are only suitable for the lower amount of traffic that the preview product will have compared to the "real thing". I would hope
that once we reach RTM the two present forums would be made read-only and a completely new set of forums (in number something between the rather too few forums for SP 2010 and the rather too many forums for pre-SP 2010) be created.
At that time I would hope that both the comments in this thread (forum names starting with SharePoint 2013 and two different developer forums for the two different kinds of development) would be included in the product team's deliberations along with them
noting the problems that the rather too few SP 2010 forums caused. At the same time they (the product team) should insist that both the MSDN and the TechNet forum systems locate all the SP forums (pre-SP 2010; SP 2010 and SP 2013) adjacent to each other in
their list of forums and in the section beginning with the letter "S" [again learning from bad experience in the past]. It's not enough for the product team to create good names for the individual forums, they also need to ensure that users find the correct
forum which they won't do if (say) the SP 2010 forums are listed under "M" and are thus reached first when scrolling down a total list of forums and they can only do this by monitoring what the TechNet and MSDN forum people do with them (= where they list
them)
