I've recently updated the GerritCommandLine tool [1] so that you can use it to manage incoming reviews.
gerrit.py --reviewee jdlrobson --gtscore -1 Will show all patches across all projects that have you down as a reviewee and are currently not negatively reviewed.
There are various other helpful filters. e.g. only show patches that have been open over X days, run it on a given repository via project.
If you are having trouble not knowing what to review or what needs review give it a go!
Thoughts and patches welcomed!
