According to the GData API (http://code.google.com/apis/gdata/ reference.html) you should be able to fetch a request for the following url:

http://blog.mobocracy.net/feeds/posts/-/-misc

and Google should return an atom listing of all posts without a "misc" label. This doesn't happen though, instead you get an HTTP 400 response (Bad Request).

Java code trying to fetch the appropriate URL throws the following exception:

[java] com.google.gdata.util.InvalidEntryException: Bad Request [java] Negations not supported yet

Although the documentation seems to think negation is possible, the service does not. Is there any ETA for when this feature might be completed? Thanks.
