But it's not open source - and never claimed to be, therefore any comparisons with open source are specious.
The only thing that is open, is that the downloadable directory / RDF dump, is open to free use, providing the terms of use are respected.
It's also pointless to ask to get confirmation that you submiited to the correct category, since until an editor reviews the site, no-one knows you submitted to the wrong categroy. Once an editor finds you submitted to the wrong categroy, he/she then moves it a more correct category, but that new category might be in the domain of another editor, thus the delay. There is no point is taking the time to tell you at that point you submitted to the wrong place and it got moved, since it provides no usefull information on which you can act. If anything it might just create false expectations that your site is about to be listed.
