‘nother little step toward web respectability
Now when you upload some data it checks that the number of posts and the number of tags are more than 1. And it only stores it in that case. It is not so important for data that is empty, but to filter users that try to store data in the wrong format. If the format is wrong the system will not recognise neither posts nor data. Thus it is useless to store it. Also it stops people from posting wrong data and then have the expectation that I might be able to magically make a mindmap out of it.
